Install PyTorch

Install the other packages

cd vocal-remover
pip install -r requirements.txt

Usage

The following command separates the input into instrumental and vocal tracks. They are saved as *_Instruments.wav and *_Vocals.wav.

Run on CPU

python inference.py --input path/to/an/audio/file

Run on GPU

python inference.py --input path/to/an/audio/file --gpu 0

Advanced options

--tta option performs Test-Time-Augmentation to improve the separation quality.

python inference.py --input path/to/an/audio/file --tta --gpu 0

--postprocess option masks instrumental part based on the vocals volume to improve the separation quality.
Experimental Warning: If you get any problems with this option, please disable it.

python inference.py --input path/to/an/audio/file --postprocess --gpu 0
