HS-TasNet

Implementation of HS-TasNet, "Real-time Low-latency Music Source Separation using Hybrid Spectrogram-TasNet", proposed by the research team at L-Acoustics

Install

$ pip install HS-TasNet

Usage

import torch
from hs_tasnet import HSTasNet

model = HSTasNet()

audio = torch.randn(1, 2, 204800) # ~5 seconds of stereo

separated_audios, _ = model(audio)

assert separated_audios.shape == (1, 4, 2, 204800) # second dimension is the separated tracks

With the Trainer

# model

from hs_tasnet import HSTasNet, Trainer

model = HSTasNet()

# the musdb dataset

import musdb
mus = musdb.DB(download = True)

# trainer

trainer = Trainer(
    model,
    dataset = mus,
    batch_size = 2,
    max_steps = 2,
    cpu = True,
)

trainer()

# after much training
# inferencing

model.sounddevice_stream(
    duration_seconds = 2,
    return_reduced_sources = [0, 2]
)

# or from the exponentially smoothed model (in the trainer)

trainer.ema_model.sounddevice_stream(...)

# or you can load from a specific checkpoint

model.load('./checkpoints/path.to.desired.ckpt.pt')
model.sounddevice_stream(...)

Training script

First make sure dependencies are there by running

$ sh install.sh

Then make sure uv is installed

$ pip install uv

Finally, and make sure the loss goes down

$ uv run train.py

For distributed training, you just need to run accelerate config first, courtesy of accelerate from 🤗 but single machine is fine too

Experiment tracking

To enable online experiment monitoring / tracking, you need to have wandb installed and logged in

$ pip install wandb && wandb login

Then

$ uv run train.py --use-wandb

Test

$ uv pip install '.[test]' --system

Then

$ pytest tests
