livefader VS demucs

Nice work on Scheme for Max!

Much less impressive, but I spent a bit of time building a simple M4L device a while back using Typescript, and put some effort into figuring out how to make TS play nice(r) with the M4L API (the JS support in Max is pretty basic).

I never got around to splitting it out into its own reusable module but it might be of interest to anyone interested in playing with scripting Ableton from Max, but not interested in learning Max’s visual programming paradigm: https://github.com/tomduncalf/livefader

Would be interested to know how Ableton’s scriptability compares to some other DAWs… I know Tracktion and Bitwig have some degree of JS support, and Reaper has its own scripting language. Personally I’d love it Ableton made the Python API etc. a bit more official but I can of course understand why they don’t.

Yeah Max’s JS support is pretty weird.

I spent some time figuring out nicer ways to work with it in order to build an Octatrack-style parameter crossfader for M4L, it provides some abstractions and setup to make using Typescript with Max a bit more pleasant. Still plenty of limitations but I was able to get my device working pretty well in the end. Apologies for lack of docs!

I've had the best results from Facebook's DEMUCs. It's not too difficult to install, and I like the sound quality of their mdx_extra model. This is the command line I use (this will use the 2 stem version -- vocals, and everything else)

For those interested, Facebook's Demucs page (https://github.com/facebookresearch/demucs) gives performance comparison for several models including open-unmix.

See also: https://www.stemroller.com This runs as a local app on Windows and Mac.

Demucs [1], one of the leading/SOTA systems, has an experimental 6-source model, `htdemucs_6s`, which adds piano and guitar:

>We are also releasing an experimental 6 sources model, that adds a guitar and piano source. Quick testing seems to show okay quality for guitar, but a lot of bleeding and artifacts for the piano source.

I also believe Audioshake [2] (a company in the space) is doing guitar separation as well.

I don't know which one /u/DarkMemoria used exactly but I use demucs. If you go to the Colab section you can run it by putting the audio files you want to separate into Google Drive.

Demucs v4 is the best open source currently, that's also what the snippet from the video sounds like uses

already exist, for example I use demucs to separate songs into 6 tracks, and then I mute what i need to be silenced in any daw.

I regularly use demucs (https://github.com/facebookresearch/demucs). It might be overwhelming when you are not used to work with the terminal, but it's as good as all the wrapper sites that ask for payment. Also, there are probably GUI projects that makes it even easier.

There's also the open source software https://github.com/facebookresearch/demucs which I assume is what many of the free websites are using behind the scenes. There's a demo site here: https://huggingface.co/spaces/akhaliq/demucs but I haven't tested it for time limits/upload limits etc.

I used demucs to try and separate the vocals from the instrumental with fairly decent results. When playing the instrumental you can still vaguely hear some remnants of the vocals and I worry when it's played over a real sound system at the wedding it will be very obvious.
