Sound Squash is a technology by Punchcard Engineering.
It is similar to (but was developed without knowledge of) premiere Pro REMIX:
Sound Squash can automatically lengthen or shorten music to any desired
duration. The algorithm does this by finding seemless cuts and recombining
pieces of music. You can try it on your own MP3 below.
Examples
Original (3:14 = 194 seconds):
Shorter version (2:21 = 141 seconds):
Longer version (3:55 = 235 seconds):
We can really push the system, here is a tiny 46 second version:
Can you put this in Davinci Resolve / Logic Pro / My Favorite Software?
I'd love to! If you work for one of the companies behind these editors, please

Why does it take so long?
The Sound Squash algorithm was developed as a tech demo. It can be further
optimized and integrated with other software.
Does it work every time?
No. Some music doesn't have enough repetition to be cut short or extended by our
algorithm, and it will sound bad or fail completely. But in most cases, Sound
Squash works reasonably well.
What is your privacy policy?
The file you upload is on a server for the duration of the analysis, and is
deleted immediately afterwards. No human(s) look at that file. Some metadata is
logged (like file size, length of the MP3, the target length) but nothing that
could be used to identify anyone.
