ChimeraNet

An implementation of music separation model by Luo et.al.

Getting started

Sample separation task with pretrained model

0. Prepare .wav files to separate.

1. Install library pip install git+https://github.com/leichtrhino/ChimeraNet

2. Download pretrained model.

3. Download sample script.

4. Run script

python chimeranet-separate.py -i ${input_dir}/*.wav \
    -m model.hdf5 \
    --replace-top-directory ${output_dir}

Output in nutshell

• the format of filename is ${input_file}_{embd,mask}_ch[12].wav.
• embd and mask indicates that it was inferred from deep clustering and mask respectively.
• ch1 and ch2 are voice and music channel respectively.

Train and separation examples

See Example section on ChimeraNet documentation.
