Demucs is a Music Source Separation tool for extracting 4 stems - Drums, Bass, Vocals, Synths. It's by far the best one I've heard.

You can find the GitHub project here - https://github.com/facebookresearch/demucs

We will be installing it in the cloud, using Google Colab, and processing tracks with the default model that it comes with. You can also read how to train it with your own dataset.


STEPS:


1. Download this archive and upload the folder "Demucs" to your Google Drive.

2. Go to https://colab.research.google.com/ and click on "Upload".

3. Download this file and upload it to Google Colab.

4. Play all the steps in a row, waiting for each one of them to finish first.

Disclaimer: The second step sometimes could take very long time to finish. Some time it will be 2 minutes, other times - 15 minutes. I can't fix that.

5. When you get to the fourth step, click on the orange/pink text and only edit the name of the song with your chosen one.
Make sure the extension (.flac/.wav/.mp3 etc.) is correct. The song should be found straight in your Google Drive.

First, it will download the pre-trained model, which takes about 4-5 minutes, and after that, it will split your song which takes roughly the same time, if not quicker.

6. After you've played the last step (exporting your stems to your Google Drive), you should find your audio files in a new folder "separated" >> "demucs_extra".

Disclaimer 2: Most of the time, it picks up background vocals as synths, though not all of them. This is a known downside.

@djtayz I get to step 4 and get this:

#STEP FOUR - REPLACE WITH YOUR SONG NAME AND EXTENSION
!python3 -m demucs.separate -n demucs_extra --dl "/content/drive/My Drive/EMIBV.flac

/bin/bash: -c: line 0: unexpected EOF while looking for matching `"'
/bin/bash: -c: line 1: syntax error: unexpected end of file.

Make sure the path to your song has quotations marks. Maybe try removing the number three from "python3"?

It was the missing quotations in it. I'd mention that in the main post just for good measure and also with an actual track example listed. But it's working now. I realized the quotes part just before seeing the reply.

@chilinvilin you gotta try this. Works the same as the other one.
