Extract vocals from any song

[pongasoft]

Although it is not purely Reason oriented I wanted to share it here since it could be useful in many cases:

I wrote a small python script to make it easier to extract the vocals from any song using the Deezer open source spleeter docker image.



Tested on macOS with Docker (and python 3) installed.

Code: Select all

# Example:
# > cd /tmp
# extract_vocals.py '/Users/ypujante/Music/iTunes/iTunes Music/Music/Janet Jackson/Janet/08 This Time.m4a'
# Generates /tmp/08 This Time/vocals.wav and /tmp/08 This Time/accompaniment.wav

The first time you run the script it will download the image (which is about 1GB compressed as it contains the neural network training data). After the first time, it won't have to download it again.

It takes about 35 seconds (on my mid 2014 macbook laptop) to process one song which is really not bad.

This process is used live in VirtualDJ for example.

Interesting stuff. Thanks for posting.

Thanks! For noobs, maybe we need:
Step by step to run on Windows?

Thank you very much for this nice little playground!

I can confirm, it also runs out-of-the-box on Linux (Ubuntu 20.04).

However, the results seem to be highly depending on the mix quality of the original song.

1. A-Ha - Take on me: overall good quality, few artifacts and the Karaoke file is also quite clean. Not perfect, but usable.

2. A 15 year old Synthpop file from a Swedish band, self-produced and uploaded to a music sharing platform: no way! Vocals sound worse than a Bell Telephone from the 1880s. And the Karaoke file is plain garbage.

But it is fun to use!

There's a pre-built version of SpleeterGUI available here that makes the process rather straight-forward.

I’ve also used virtualDJ (free) to good effect. As the latest version has real-time track separation.

As madmacman said... the results very much depend on the original recording

VirtualDJ is using the same product under the cover as listed on the github page. So I assume the result should be identical.

You can also extract vocals from any song using the recently released version of Izotope RX8:-
