Best-In-Class Audio Slow Down
and Key Change App

Mac OSx 10.8 - 14.X
Win 7 to Win 11

Song Surgeon was first released in 2007, and is now a decade old... From its first humble beginnings it has grown to be one of the most popular and valuable tools used by musicians – both students and teacher. At last count Song Surgeon has been sold in more than 120 countries worldwide – and by musicians that play 37 different instruments.

Our newly released Version 5 of Song Surgeon takes the program to a whole new level with the addition of key detection, automatic beat detection, and chord detection. What that means is that when you open a song, Song Surgeon will automatically detect the tempo of a song in BPMs, in will determine the key signature, it will detect the chords – and it will display all of this information on the main user interface so you can see and use it. We know of no other audio slowdowner software that provides these three features in one program. And of course, that’s just the beginning.

Version 5 of Song Surgeon takes the program to a whole new level with the addition of key detection, automatic beat detection, chord detection.

In addition to providing nearly flawless, distortion-free key and tempo change of audio, Song Surgeon has a long list of other useful features:

Here's just a sampling of what Song Surgeon can do for you!
Chord Detection Saves Time, Accelerates Learning
The chord detection features will detect the chords of a song and immediately display them for you to use. You no longer need to search for chords or tablature on the internet. Additionally, the Pro model makes these chords along with their time stamps available for printing so you can take them with you.
Speed Trainer Allows You To Learn Faster
Speed Trainer is a function within a looping area that automatically increases or decreases the speed of playback each time it loops, based upon our customized settings. You select a beginning and ending tempo – and a percentage change, and Song Surgeon will do the rest. Speed Trainer allows you to practice with increasing speed, thus enhancing your learning.
Isolation of Multiple Audio Segments
The ability to create an unlimited number of loops with a single audio file means you can isolate and customize each of these looping segments individually, applying different keys, tempos or EQ’s to each loop..
Transpose any song with just one click
You can transpose an audio file into another key in just one click, and then hear this change in real time, and continue to change key up or down until you get it just right. In addition, Song Surgeon's formant preservation ensures that there will be no chipmunk or munchikin vocals as you apply key changes to your song.
Helps you strip audio from almost any video
In addition to opening most standard audio files, Song Surgeon also can open and strip the audio from most standard video files. Once you have stripped the audio from a video, it will open in Song surgeon and then you can save the audio in any standard audio format.
Automatic Click Track Creation and Insertion
Based upon the detect BPM of a song, Song Surgeon can create a 4 beat click track at the exact tempo of the song and insert it at the beginning of your audio file.
Helps you create library of customized, edited audio files
Thanks to the export feature in Song Surgeon you can create new audio files with your changes embedded. These files are permanent and portable and can be used on any standard audio playback system. (CDs, iPod, mp3 player, smartphones, etc.)
Helps you learn music or a song much quicker and easier
By slowing it down significantly, without distortion, to any tempo that you prefer. Our surveys show an increase in learning of 2 - 10 fold with an average increase of 614%.
Metronome Synchronized with Tempo
Song Surgeon’s built in metronome is automatically synchronized with the tempo of each song as you open a song file. The independent volume control of this metronome allows you to change volume as desired, allowing you to hear the metronome over top the song,
31 Band EQ
Song Surgeon Pro’s 31 Band EQ allows you to provide laser-like control over the frequency changes applied to a file. It allows you to enhance specific instruments or sounds and diminish others. These EQ changes can be permanently applied and saved in a new file.
Vocal or Instrument Isolation
While you can’t create a Karaoke type track from a final mixed track with multiple instruments, by using Song Surgeon’s VR Slider in combination with the 31 band EQ, you can diminish or enhance specific instruments within a mix making it easier to hear only that frequency or sound you are most interested in.
Basic Recording / Editing Functionality
Song Surgeon has basic editing and recording functionalities. While not built to replace high end audio software like Cubase or Pro Tools which cost many hundreds of dollars, many Song Surgeon customers find its more modest editing and recording features quite useful for many situations where pro quality editing or recording is not required.

Song Surgeon Delivers the Highest Quality Audio

H. Exley
I was using Cubase LE for changing the key and speed of a song. With Cubase LE there was distortion if the change in speed was large. With song surgeon there was no distortion. I use song surgeon to make karaoke discs.
M. Johnston
I also love the fact that the sound is so clear even at super slow speeds. I have a Tascam CD unit for slowing down music and can tell you that there's no comparison. The Tascam unit is very distorted at slow speeds, which makes it more difficult to figure cut the notes.

Frequently Asked Questions & Answers

1. On What Operating Systems Does Song Surgeon Run?

SS V5 runs on Mac (OSx) and Windows. Specifically this is OSx 10.8 - 12.x and for Windows 7 – Win 11. Some of the machine on which the older OS’s are installed may not have sufficient resources to run Song Surgeon 5 well.

2. Will Song Surgeon V5 run on mobile devices?

Song Surgeon V 5 is a desktop application. We do have a “lite” version of Song Surgeon, called, Song Surgeon Trainer available as an app. It is free and can be found on both the Google Play and Apple Stores.

3. What Are The Computer Hardware Requirements for Song Surgeon?

Here are the suggested requirement for running Song Surgeon Version 5.

(Windows XP – Win 10)
  • 2.0 GHz CPU with dual-core processor minimum (Recommended: Quad-core i5 processor or better)
  • 4 GB RAM minimum (Recommended: 8 GB or more)
  • 200 MB of hard-disk space for program installation
  • Display dimensions of 1024x768 or greater
(Mac OS X 10.8 or Newer)

  • 2GB of RAM (Recommended: 4GB of RAM or greater)
  • 200 MB available disk space for program installation
  • Display dimensions of 1024x768 or greater
4. Why Does SS V5 Not Have A Sniffer Module in it like earlier versions?

In the past, Google among others, have sued to block some products that perform downloading functions. However, it’s important to remember that many uses of copyrighted material are considered legal under the fair use doctrine to U.S. copyright law. The fair use doctrine makes exceptions for non-infringing purposes like news reporting, research, education — or just for laughs. Consider YouTube’s first big legal copyright challenge, a 2007 video of a baby dancing to the Prince song “Let’s Go Crazy”. Universal Music Group, the copyright holder of that hit song, sued the baby’s mom for copyright violation. A judge ruled in favor of the mom and the baby, citing fair use.

Two things have happened recently that concern us. Once is that Google has terminated one of our Adwords accounts citing the downloading module as the cause. Even more recently Google has sent a cease and desist letter to a company that sells a YouTube Downloader application, similar to what we provide in Song Surgeon.

Because of these developments we have made a business decision to remove the downloading (Sniffer) modules from Song Surgeon Version 5. We have a similar module in our product Video Surgeon and will also be discontinuing it, when a new version of that product is released.

Version 4 of Song Surgeon will not be affected by this decision and it will continue to contain the downloading modules. However, like all older versions of our products, now that a newer version has been released, it will no longer be updated. Accordingly if this downloading module ceases to function at some point in the future we will NOT provide support for it or fix it.

We know that many customers use and like this downloading feature. What we have done is to consolidate the downloading module found in our other products into a single product called Download Surgeon; plus we have added additional capabilities. This will allow customers who want these downloading features to be able to access them, while at the same time, limiting our business exposure and shielding our main products, like Song Surgeon, from any adverse affects.
