demucs VS Demucs-Gui

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)

facebookresearch/demucs: Stem seperation

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.

If downloading a script and/or using the command line is too technical for you, you can get free GUI for it here.

use demucs. gotten pretty decent results with it. keep in mind that there will always be artifacts

If there's other sounds on the centre channel you could also potentially run it through vocal isolation processing (e.g. the Music Rebalance tool in iZotope RX software). There's paid software that does this, but also free software out there that can do this but lacks the creature comforts of a nice user interface (E.g. demucs-gui or Ultimate Vocal Remover).

Needing a GOOD stem separation for an upcoming set, I decided to go down the linux and python rabbit hole this evening and compile DEMUCS myself. But there in the documentation was a link to a pre-compiled GUI version! https://github.com/CarlGao4/Demucs-Gui/releases

Here is also a free program that you can run on your own computer that uses the same algorithm: https://carlgao4.github.io/demucs-gui/

Depending on what quality you need, maybe a AI stem separator would be good enough? For example https://carlgao4.github.io/demucs-gui/

You can look into Demucs GUI. It's an AI music seperation tool developed by Facebook AI research. There are other music seperation tools like Deezer's Spleeter which I think is the music seperation engine used used in iZotope's RX10 (at no cost). Demucs is ime is the best at isolating vocals if you use the unquantized trained modelsi.e mdx and mdx_extra. Personally I find mdx_extra the best trained model for Demucs.

Try Demucs-Gui. It's free. And amazing.
