Audacity audio Editor vs. Song Surgeon 5

Audacity is a free, open source software for recording, mixing, and editing sound. Although it is not nearly as sophisticated (or expensive) as something like PRO Tools, Audacity is a decent editing and mixing piece of software. It is also reasonably easy to use. Contained within the list of features and functions in Audacity is the ability to change tempo and key. Although Audacity does perform these functions, the quality of the resulting audio is not particularly good. Tempo change (slowing down or speeding up) can be accomplished independently of pitch, but as you decrease the tempo you quickly begin to hear artifacts and distortion with decreasing tempo to the point that the result audio is unusable.

A much better way to change music, song or audio key is with Song Surgeon. There are two different ways to accomplish this with Song Surgeon. One is with our desktop software, which costs money but provides the highest quality audio after key and tempo change. We’ve heard from people that own Cubase, ProTools and other high end software programs and they have reported that the audio quality from Song Surgeon is equal to or better than that from these programs costing many hundreds, and in some cases thousands of dollars. The second method is to use our free online service. Let's briefly review both.

The Song Surgeon online pitch and tempo change is free and, importantly, the sound or audio quality of the pitch and tempo changes is good. It is NOT as good as what we have in our desktop version but it should be adequate for most situations.

If you start with a file of borderline quality, then the resulting file may have quality issues.

The first is for voice or a single instruments (V algorithm), one is for small changes of +/- 15% (P algorithm) such as those you might make when changing a file 1 or 2 half steps to for performance purposes. And the last (T algorithm) is for large changes such as those you might make to better hear something for learning or transcription purposes.

In addition to these standard default algorithms, Song Surgeon allows you to change the algorithm parameters to give you even higher quality than these three standard ones.

Lastly, Song Surgeon has formant preservation built into it. This is a function that eliminates the munchkin or chipmunk effect heard in vocals as key is changed. This is a must-have feature when you are transposing audio files that have vocals. While the slow down technology remains the most commonly used feature found in these types of programs, and musicians remain the most common users, the new version of Song Surgeon with its many new functionalities will certainly open the door to use in many other fields such as dance, exercise classes, transcription, karaoke, translation, and worship music, to name a few.
