this is very handy, someone built a M4L device that runs spleeter on any audio you’ve highlighted in ableton. for those unfamiliar, spleeter is an open source tool that using some form of magic to separate songs into vocal,drums,bass,‘other’ stems. if you have only gotten into sampling recently i would describe it as “not perfect”, but if you are familiar with the issues in trying to do separation at all i would describe it as ‘actually fucking crazy’. i remember when this was considered to be impossible, when everyone started trying to use phase inverted instrumentals to do it, and feeling like a genius for being able to get better results than that via spending hours manually painting out the instrumental in izotope RX (sincerely, the joke was on me). so getting equivalent or better results in like a minute now puts me very much on the “is this actually magic?!”
i first encountered it via melody.ml which is a great way to try it out but a)is limited to MP3s and b)only lets you try a couple of songs for free. have not noticed any quality difference between mp3 separation and wav, but seems like it can’t hurt?
the set up is more of a pain to do than any other M4L device, but to be honest i have been trying off and on to build it as a standalone app and i never had much luck with it. following the github instructions for this version actually had me up and running in like 20,30 minutes.
it requires you to install another app, docker. makes me wonder what other things i could potentially be using it for.
