Record Level will open your system audio settings. Once you have selected a recording device, you can then from there
select the Device you want to use for recording. You can select its properties and then adjust the recording level. A picture of
this looks like on a Win 7 machine is shown to the right. Please note it is very important that you reduce the volume enough,
so you don't cause clipping (distortion) in the audio you are recording.
The level meters that are found in the recording dialog window
will give you an approximate idea; however, we recommend you do a dry run of a few seconds, keep it, and then once it opens in SS you will
be able to more easily see the levels and make further adjustments if necessary. Since SS can easily increase the volume of recorded
audio, it is best to err on the low side, making sure that whatever you record does not clip. Distortion from clipping cannot be removed in
SS; however, low volume recording can be amplified using the change volume settings in the Edit function of Song Surgeon.
Most computers have multiple recording devices installed - and every computer is different. We cannot, in this User Guide,
illustrate all possible options, so if you want to use this function, please know that you will need to spend a significant amount of time
experimenting until you get the correct settings for YOUR computer. Please see the training video on recording for additional details; this can be accessed through the Help Button on Song Surgeon.
A final note:
Some computers may not be able to record system audio because they don't have a sound card that will allow this. This is more common on older computers with older operating systems. There is at least one work around for this and it can be found in the Knowledge Base of the Help Desk for Version 4 by searching for Recording.
- Before you can execute any of the Edit functions, you must first select an Edit area. This is done by holding your left mouse
button down and dragging your mouse in the Wave Form area. This will begin highlighting that area of the wave form file and continue until
you release your mouse button. You can adjust the placement of this highlighted area by grabbing it at the beginning or end of this selected
area and moving it. To deselect a selected edit area, tap the Escape key on your keyboard.
Once you have selected an area to edit, click the Edit button and open the Edit menu. The following selections are available. (There are also
keyboard shortcuts for these).
The use of the editing commands Paste and Insert Silence are done not by selecting an area of the wave form file as described above.
Rather, these commands are executed using the progress indicator as the insertion point from which data is pasted or silence is
You can cut, paste, and copy within the same instance of Song Surgeon
, or you can open multiple instances
and cut, paste, and copy between
them. This new version has a built-in automatic converter
that will detect mismatches of frequencies
and bit depth when you are attempting
to paste, and automatically convert these to match the destination file to allow you to execute this operation.
- This deletes the highlighted section but place a copy of it on your clipboard.
- This copies the highlighted section to your clipboard.
- This copies what is on your clipboard into the wave form file by inserting it at the current position.
- This deletes the highlighted section.
- This inserts silence -- of a length you specify -- into the wave form file at various positions
Silence Highlighted Section
- Choosing this option AFTER selecting a portion of the wave form file will silence the selected area.
- This allows you to increase or decrease the volume of the selected section of the wave form.
Fade In / Fade Out
- By selecting an area of the wav for data and then selecting one of these two options, the volume of the wav data selected will be gradually increased (Fade in) or decreased (Fade out) to allow smooth entrances and exits to audio segments.
Mix Down Stereo to Mono
- This option will take the stereo file open in Song Surgeon and combine it to one, thereby creating a mono file. There are two options. If you select a portion of the data on the screen, SS will mix down ONLY the selected portion. If you do
not select any of the wav data, SS will mix down the entire audio file that is opened.
Convert Mono to Stereo
- This option allows you to create a stereo track with 2 channels from a mono track that only has one channel. When this option is selected, a submenu opens which allows you to use the mono data in one of three ways. You can place it in the left channel (with the right channel being blank), or the right channel (with the left channel being blank), or you can place it in both channels.
Change Sample Rate
- Changing sample rate is the same thing as changing the frequency of a file. SS allows you to convert the file you have open to one of several other frequencies.
- This effect can be used at any time but is primarily used when applied to audio that has been recorded from old vinyl
or LP's. This removes the majority of pops or clicks associated with such audio.
- This will undo your last action and will continue undoing as many as 10 previous actions. This undo encompasses all function
found on SS including zooming as well wav form selection for editing.
- The opposite of undo, it will reapply previous actions that you have undone.
- This button toggles between float and fixed states of the progress indicator. In the fixed state, the progress indicator
is centered in the wave form area, and the wave form data moves while it stays fixed. In the float state, the progress indicator moves or
floats over the wave form data and the wave form data is fixed.
- The Marker button, when clicked, inserts a marker at the current position of the progress indicator needle in the marker area
above the wave form window. You can also insert a marker by left-clicking with your mouse in the marker area of the wave form window.
Markers can be edited by hovering your mouse over the inverted blue triangle and right clicking. A menu will appear that will allow you to
delete the Marker or change the name. Markers can be moved by hovering your mouse over them and then left-clicking and dragging the
marker to a different position.
- EQ settings can be designated for an entire song, or applied to a single loop or to each loops individually. These settings will
be applied to any file that is EXPORTED from SS. The Standard version of SS has 9 band EQ.
There are a small number of presets in the
9 band EQ and you can create new ones and delete these at any time.
The Pro version of SS contains a 31 Band EQ.
With a thirty-one band graphic equalizer, each band covers one third of an octave (you can
work this out from the fact that one octave represents a doubling - or, going the other way, halving - of frequency, and there are ten
octaves between 20Hz and 20kHz: on a 31-band graphic there are three steps between each doubling of frequency). This EQ configuration
provides a great deal of control over frequencies and therefore over the sound you hear. This sophisticated EQ configuration is very useful to
musicians or people that transcribe music, as it allows them to diminish unwanted sounds and to enhance others.
In Song Surgeon Pro, this 31 band EQ comes loaded with more than 60 presets that have been custom-built on an instrument basis. The list of
instruments is not comprehensive, but we have included the most commonly played instruments in this list of presets. For each instrument, we
have a preset designed to enhance that instrument as well as diminish that instrument. These are not perfect, as every song has a
different mix of instruments and frequencies and, not only will one size not fit all, EVERY song is likely to require customization of the
EQ preset to best work for that song. Nonetheless, these EQ presets are helpful starting points.
The Pro EQ allows you to create new custom presets and delete them. Unlike the Standard EQ, the 31 band found in Pro allows you to
apply the EQ to either of the two stereo channels or to both.
To make this EQ compact, we did not label all of the bands, but by hovering
your mouse over any slider you can see what band it is for. Also notice here on the left side that we have a pre-amp that can be used to increase the volume. This is especially useful when you are cutting bands and you need to pump up the volume to hear the remaining frequencies.
Notice that the gain is +30Db and the cut is -60Db. Please note that if you increase the gain substantially it is likely that you will introduce clipping and distortion. Also note that if you cut a band significantly, you will reduce the volume substantially.
Notice the color coding -- when flat, the sliders are gray; when boosting, they are green; when cutting, they are red, and if they are turned OFF, they are BLUE.
There is a lock icon here in the middle. When turned off, you see sliders for both left and right channels, and these sliders can be moved independently. When locked, the bands for the channels move together and whatever you do to one, you do to the other. In the locked state, the EQ goes into a mini mode, and only one set of bands is visible and necessary for the locked channel adjustments.
Bands can be adjusted in several ways.
The first way is by grabbing a slider with your mouse (left click) and moving it up or down.
A second way is to click or click and hold down the mouse in the groove for that EQ band -- it will move incrementally up or down.
If you want to move multiple sliders at once, you can right-click and drag your mouse across a series of bands, and the sliders will move to the location of your mouse drag.
Lastly, for fine tuning, you can select bands by holding down the control key + clicking with your mouse on a band
. You can select one or multiple bands. Once you have selected the EQ bands of interest, you can then nudge them up or down (for fine tuning) using your up and down arrow keys.
The last area to review regards the presets. System presets cannot be modified or erased
you can create new presets based upon the existing ones by selecting a preset, modifying it to meet your needs, and then saving it with a new name. To create a new preset, you click the button with the green + sign, give it a name, and the click okay -- this will create a new preset. If you want to save this new preset permanently so that it stays in the list of presets, you must click the button with the BLUE arrow to save it. The delete button will allow you to delete ANY custom preset, but it will NOT allow you to delete System presets.
If you right click in this preset area
you will see some additional selection appear. These selections will enable you to sort the list, or filter the list, so that you can get the group of presets on your screen that you would like to use. To refine your list further, you can also use the hide/view button to hide or remove presets from the visible list.
Once you have refined your list of presets, you will need to click the SAVE button (blue arrow) to save this list of presets so it loads the next time you open SS.
Lastly we will discuss the EQ-B button (which is the EQ bypass button). If you have a song open and playing in SS and you have EQ applied to it, selecting the EQ Bypass and toggling it on will ignore the currently applied EQ and the song will continue playback with no EQ applied. Note that when you do this, the buttons become blue and inactive/you can't move them. When you toggle the bypass off, the EQ is again applied to the file and the buttons are re-activated.
EQ is a topic that can be very complicated. There are entire courses in college dedicated to it, so don't expect to master the use of this
31 Band EQ overnight. If you'd like to learn more about EQ, we refer you to this external site which provides an excellent overview:
13. Music Pad
- Music Pad allows you to create and store text note, music tablature and conventional music notation. Whatever you create within Music Pad can be stored when you save an open file as a Song Surgeon Project file (.ssp). All of the contents in Music Pad will then be recalled when you re-open this project file at a later date.
- There are three toolbars found within Music Pad. The main toolbar which appears below has the following functions.
A. This button toggles your screen back to the main Song Surgeon interface.
Music Notation Toolbar
B. This button opens the music notation toolbar.
C. This button displays or opens the tablature toolbar.
D. This is a print preview button.
E. This is a print settings button.
F. This is the print button.
G. This is an undo button.
H. This is a redo button.
- Standard music notation is quite varied and quite complex. Music Pad allows you to create basic music tablature and gives you some flexibility when doing so. Keep in mind that Music Pad is not intended to be a complex Music Score program; rather, it is an auxiliary feature found within Song Surgeon that allows you to create and store basic music notation.
The Music Notation toolbar is shown below.
The standard music notation toolbar allows you to create basic standard music notation like that shown below. Note the basic layout. It is like an online sheet of paper. The inner gray line represents the margins or useable area for printing purposes. It is within the gray boundary line that you will create your music.
This is a text notes button that allows you to enter text onto your music notation via a text box. Within the text box you can control the font size, the orientation, the font color, and the font.
This music symbols font enables you to enter additional, less common symbols that are not available from the notation toolbar. For example, the following symbols can be created by typing the following characters into the text form.
This is the staff button. When clicked -- if you move your mouse onto the music pad paper and left click and drag to the right -- you will create a grand staff. If you also pull or slide your mouse downward as you do this, you will create 2 staff lines simultaneously.
All objects placed on this cyber paper have selection handles on them that appear as a square box in the upper right and lower left corners of the object. These handles, when they appear, tell you an item(s) is selected and allows you to move or reposition the selected item(s). ALSO: Once you have drawn an object and positioned it on the paper, you must left click to place that object onto the paper.
This Clef button allows you to select a clef sign from the dropdown box and place it on the staff.
The clock is the icon for the tempo. You can select from any of the tempo presented in the drop down list. If you also want to include a numerical designation of tempo, like for example, 120, you can do this by using the text tool mentioned in (LETTER I).
This time signature button allows you to select from any of the normal time signatures and place it on the staff.
The flat/sharp button allows you to select either one and place this on the staff.
O. and P
. These are beginning and ending repeat signs that can be selected and placed on the staff.
This button is a vertical measure line for delineating measures.
These are buttons for individual notes beginning with a whole note and decreasing to a 128th note. All of these notes have the tails pointing upwards. However, there are many circumstances in which the tails of notes point downward. To flip these notes by 180 degrees so that the orientation of the tails is downward, select the note from the toolbar with your left mouse button. As you begin to move your mouse with the note attached, right click and hold down and you will see that the note has been inverted. Continue dragging the note to the position on the staff where you would like to insert it. While your right mouse button is being held down and the note is inverted, click the left mouse button and this will place the note, in an inverted position, onto the staff.
IN ADDITION -- these same buttons (S-Y) also double as REST buttons. You can toggle to see the rests by holding the Control key down. When you do this, you will see the corresponding rest notes displayed. While holding the control key down and with the rest being shown, you can select a rest and place it onto the staff.
This is the half dot, which when placed after a note increases the length of the designated note by ½ or 50%.
This is a triplet button, which allows you to create a triplet line that can be placed above a group of three notes to designate them as a triplet.
This button allows you to create a tie of an indeterminate length. It can be stretched to accommodate any number of notes AND it can be rotated so the arc opens upward or downward.
Repetitive Insertion: If you need to insert the same object onto Music Pad, you can do this by using the space bar. For example, let's say you are inserting a measure of quarter notes. Rather than having to go to the toolbar four times, go there only once and select the quarter note. Place it on the staff, and after placing it, tap the space bar. Immediately you will have a second quarter note to also place. After placing this note, tap the space bar again for another quarter note. You can do this an infinite number of times.
Because rests are viewed by using the control key, if you want to repetitively insert a rest, you follow the above procedure with the exception of hitting the Control key down and then tapping the space bar.
- The toolbar below is the Tablature Toolbar. It contains four buttons as described below. Anyone that is familiar with tablature knows that there are many different forms not only between instrument types but even within the same instrument. Accordingly, we have created the tablature part of this program to be flexible to accommodate the specific preferences of users.
This button is a Text Block Insertion tool that has a variety of uses. It is especially useful when creating tablature. When you click this button and move your mouse to the Work Area of Music Pad, it will display and insert a text box that looks like what is shown below.
As the text says, you can drag and resize with your mouse and double click within the box to edit the text. You can also right click and you will see a menu that will allow you to resize the text by choosing alternative font sizes. This is especially useful when cutting and pasting text from documents or web pages whether tablature, lyrics or something else. The ability to resize allows you to have it fit into the work area so it visible and can be formatted correctly for printing.
This button allows you to create strings similar to the staff button in the Music Notation toolbar. It is different, though, because it enables you to create any number of strings with a minimum of two. After you click the button, you move your mouse to the main work area and left click. As you drag your mouse to the right, you can size the string area horizontally and, if you drag down, you will see the number of strings increase.
This is the button for the symbols key. When you click the drop down box, you can select from a few preset symbol keys for commonly used instruments like guitar, drums, harmonica and a few others.
When you select one of the items in the list, it opens a text editor window with the selected information. You can modify or edit this information at any time. To save these changes, you must click the save button on the text window.
When you click this button you will also see the option to create a new symbols key. This will open a dialog where you can enter the name of the instrument or some other name you will recognize; then you can enter the set or series of symbols for this new key, clicking Save on the dialog box. You have now created a new symbols key.
Symbols keys are for reference and should be altered or modified to customize them for your needs. Also, if desired, you can copy these symbol keys and paste them into the work area of Music Pad using the Text Block button #28. This might be helpful if you are going to print the information in Music Pad to share with someone else.
This button creates a line of indeterminate length. Once placed in the work area, you can grab it and change the length. This line is similar to the measure line found in the Notation toolbar, except this line can be resized. This line should be useful when creating measure markers for tablature, as it will allow you to size it to the tablature you are creating.
Important Keyboard Functions:
Space Bar - Depressing the space bar will insert again onto the Work Area the last selected object.
Music Pad Page Toolbar
Caps Lock - When the caps lock is on, the Quick Text Insert Mode is invoked. This allows you to push any alphanumeric key on your keyboard and that letter or number will be inserted at the location of your mouse.
Control Key - Holding the control key down reveals the "rests" toolbar and enables you to select these objects.
Control + Space Bar - Holding the Control key down allows you to select a "rest" and then ones placed on the work area, while continuing to hold the control key down and tapping the Space Bar inserts the same rest note again.
Left, Right, Up, Down Arrows: - When one or more objects are selected, these arrow keys allow you to nudge the object(s) in the direction of the key.
Escape - If you have selected an item from one of the toolbars by mistake and would like to deselect the item without having to place it in your work area, simply hit the Escape key.
- At the bottom of the music page frame, there is a small menu (shown below) that allows you to insert additional pages.
Other Important Features
- An object that is selected will show two small green squares or handles. If an object is selected, this means that it is active and can be manipulated. Multiple objects can be selected by clicking on these objects one at a time within the boundaries of the object. Lastly, if you want to select multiple objects in one operation, simply use your mouse and trace a rectangle around the OUTSIDE of all the objects you want to select, while holding the left mouse button down. Once you release, you will see that all of the objects within this rectangular area are now selected as indicated by their green handles.
- An object or group of objects that is selected can be nudged by using the four arrow keys on your keyboard.
- The sniffer button give you two options: the Main Sniffer and the YouTube Sniffer. We recommend that you do NOT use this sniffer for YouTube videos but rather use the YouTube downloader mentioned below.
The Main Sniffer has the ability to detect audio or video playing in your browser from thousands of other sites. It automatically detects the link and enables you to download these files, whether audio or video. Audio files are downloaded and stored on your computer directly. The sniffer window will NOT save video; rather, it extracts the audio from the video and saves this as an audio file. This sniffer technology works on approximately 90% of all web sites with A/V files.
As depicted to the right, the links are color coded. The red color indicates a link has been detected. This red turns to orange as a file is being downloaded. Once a link has been downloaded the orange then turns green.
allows you to hear a preview of the file once detected. While this preview works on most sites, it does NOT work on Youtube. The Remove
button removes the link from the sniffer window. Download Only
saves the file to your computer but does not open them in Song Surgeon. Download and Play
saves to a temporary location and then opens the file in Song Surgeon's main window.
The sniffer module works by detecting network traffic. The simple definition of NETWORK in computer lingo is two or more computers connected to each other that can communicate. What that means for the sniffer module is that it will not work (detect) video playing on your computer or video playing from a DVD. It also means that if you have already played a video from the internet on your computer, and then you view the video a second time and ask the sniffer to detect it, it will not. Why? Because in order for the video to be played on your machine, the data must be (and is) downloaded to your machine as it plays. This means that if you go back to a video to play it a second time, even though it appears that you are playing the video from the internet, you computer is really playing it from a temporary location on your computer. If you want the sniffer to detect an audio or video file you have played before in your browser, you will need to clear the browser cache. Toward the bottom of this section on the sniffer module, there is a link to a video which shows you how to do that.
The use of the sniffer is straightforward.
1. Open SS
2. Click the sniffer button to open the sniffer
3. Minimize the main SS user interface, leaving sniffer open
4. Open Browser, go to a site and play audio or video.
5. Within a few seconds of the AV file starting to play, the sniffer should detect and populate the sniffer window with a description of the video.
6. Once a link is detected, select the link with your mouse and then select Download or Download and Play.
We recommend that you manage the files in the sniffer by removing those you don't want and downloading those that you do within a short period of time after you first detect them.
We do not recommend that you populate the box with a large number of links and then go back 20 or 30 minutes later and try to download them. Some AV files have associated cookies that may expire and cause problems with downloading if you wait for too long.
The sniffer works best with high speed internet connections. If you have a slow internet connection, the sniffer module will likely not work well.
Main Sniffer Troubleshooting
Because the sniffer module is working with outside websites on which we have no control, and with your internet connection through a browser which is subject to browser security settings, computer firewalls, and your antivirus program, Sniffer is the function within Song Surgeon for which we most often receive Help Desk tickets. For that reason we are including this troubleshooting section in this User guide.
There are two main problems that are encountered. They are:
1. The sniffer module does not detect the video playing - nothing appears in the sniffer window.
2. The sniffer window detects links and you see them in the window, but when you select one and attempt to download it, it fails.
We estimate on about 85% of machines that the sniffer module will work correctly the first time it used. However, on some machines a combination of browser, firewall, and antivirus settings blocks the sniffer from working correctly and your computer may need to be correctly configured to allow the sniffer module to work. There are hundreds of different antivirus programs in use and each of them is different, so we cannot provide specific guidance for all of these. Please start by doing a search on the internet of your antivirus program and how to set up a program exception. If you have tried to get the Main sniffer to work and have failed, please complete a support ticket on our Help Desk.
Alternative (YouTube) Sniffer – With the launch of version 4, we have built and implemented an alternative sniffer module specifically for YouTube, which we call the YouTube Sniffer. This sniffer also has a built-in update mechanism to help keep the YT Sniffer up-to-date and working.
15. Vocal Reduction
To use the YT Sniffer, click the Sniffer Button at the top of the SS user interface and select the YouTube Sniffer.
Next, go to YouTube and find a video that you would like to download. Once you locate such a video, copy the YouTube URL of the video playing in
your browser. Paste this URL into the YouTube Sniffer and then select either Download or Download and Play. Song Surgeon will then proceed to download the video file and strip the audio from it.
If you have selected Download, Song Surgeon will simply download this video and store it on your computer in the sniffer folder (see Options button for this file path). Alternatively, if you select Download and Play, Song Surgeon will immediately download the video and then strip the audio from the video and open it in Song Surgeon for you to use.
- This button opens a slider that allows you to apply an algorithm to the audio file, which in some cases can be fairly effective in reducing the vocals in an audio track. Its effectiveness is song dependent. Generally speaking, it works better on older songs, where fewer tracks were employed and less sophisticated effects and mastering methods were applied. There is no prescribed best setting. We recommend trying the center section, around 128, as a starting place and then adjust up or down from there to see if better vocal reduction is obtained. VR settings are recalled as part of a Song Surgeon Project file; they are also applied to the audio file when the EXPORT button is used.
- This button contains a number of settings for Song Surgeon. These are primarily default file locations for various functions.
- This button contains a link to the Quick Start Guide, the Help Desk, and the Training Videos.
The Wave Form Window shown below consists of a Marker Area at the top, a Wave Form area in the middle, and a Timeline area at the bottom. Each of these areas is described in more detail below.
18. Marker Area
- The area at the top of the wave form window is called the Marker Area. Two types of Markers appear in this area. Blue, sequentially numbered triangles are Information Markers. These can be inserted by clicking in the Marker area or by clicking the Marker button from the top menu. These blue Information Markers can be deleted by right clicking on one with your mouse, or they can be edited. Editing allows you to enter a limited number of characters to custom label the Markers. You can also delete the markers and change the default font size from this right click menu. These Information Markers are always found at the top of this section.
The markers found below the blue Information Markers will be either green, red, or yellow. These markers are referred to as Loop Points
, because they define an area of a song that will loop repeatedly. They are also numbered sequentially. When you set the first loop point it will be orange to indicate it is not complete and is only one of a pair. As soon as you set the second Loop Point, you will see the first one turn green, signifying that it is the beginning Loop Point, and the second one turn red, signifying that it is the ending Loop Point. Loop Points are set by clicking in the Wave Form area with your mouse. A left click marks the beginning Loop Point and a Right Click marks the end. Right clicking over top the Loop Points allows you to either delete or edit the Loop Points. See the Loop Control (section #23) for more details on the Loop Point controls, as well as setting beginning and ending Loop Points from this control area.
19. Wave Form Area
- The wave form area is where the left and right wave form data is plotted in the GUI. This area of the wave form window is where you can select sections to edit and set loop points by right or left clicking in this area. A selection is made by left clicking and holding down the left mouse button, then dragging the mouse across the wave for area. As you do this, you will see the selected area turn a blue color to indicate it has been selected.
Version 4 enables you to selected data from one channel or both channels for editing purposes. If you want to select both channels, click, hold, and drag your mouse near the bottom of the center of the wave form data. If you want to select only data from one channel, drag your mouse near the bottom or top of the wave form screen and the left or right channel will be selected independently of the other channel.
The wave form data in this area also can be zoomed in to enlarge the details and to make the selection or setting of markers, loops, and edit areas easier and more accurate. To the far left of this area are small speaker icons that can be clicked to select the left or right or both channels. When in the Float mode, you can grab the wave form display with your middle mouse button (rollerball) by clicking and holding it down; then you can drag the wave form display to the left or right. If you have a notebook that doesn't have a middle mouse button, you can accomplish the same thing by holding down the Ctrl key and dragging with the left mouse button.
- The timeline area at the bottom of the wave form screen (bottom of above image) shows the chronology of the wave form data. If you click with your mouse in this area (which is below the bottom black line frame and within the numbers which designate the time position of the audio file), you will automatically move the current position of the audio to that place on the timeline that you selected by clicking.
21. P/T Toggle
- This button toggles between Performance (P) and Transcribe (T) algorithms. The graphic on the left shows this button from the user interface.
Please note that the white color shows the algorithm that has been selected or turned on. Starting with version 3.0, Song Surgeon has used a completely new sound engine for changing pitch and tempo that virtually eliminates ALL distortion -- this has only become more improved with 4.0. As part of this change, we have implemented two different algorithms. If you are using Song Surgeon to practice something and are making significant changes in Pitch and/or Tempo, you should use the "T" or transcribe setting. This setting gives you the BEST quality sound reproduction for extreme changes (for example, slowing the tempo of a song to 25% of the original).
If, however, you are going to use Song Surgeon to make a small adjustment, +/- 15% of the original (say a 1 or 2 step change in pitch) and then you want to export the file to make these changes permanently for a theoretical performance setting, then you should use the "P," or Performance setting.
If you have an older computer or one with a smaller amount of RAM memory (or both), you may experience a stuttering of sound stopping and starting on playback. If this occurs, you should right click over the P/T button and select a lower quality setting. This may improve playback performance.
