Dual-Path TFC-TDF UNet

A Pytorch Implementation of the ICASSP 2024 paper: Dual-Path TFC-TDF UNet for Music Source Separation. DTTNet achieves 10.12 dB cSDR on vocals with 86% fewer parameters compared to BSRNN (SOTA).

Notes

1. Overlap-add is switched on by default, comment the values of key overlap_add in configs\infer and configs\evaluation to switch it off and the inference time will be 4x faster.

Environment Setup (First Time)

1. Download MUSDB18HQ from https://sigsep.github.io/datasets/musdb.html
2. (Optional) Edit the validation_set in configs/datamodule/musdb_dev14.yaml
3. Create Miniconda/Anaconda environment

conda env create -f conda_env_gpu.yaml -n DTT
source /root/miniconda3/etc/profile.d/conda.sh
conda activate DTT
pip install -r requirements.txt
export PYTHONPATH=$PYTHONPATH:$(pwd) # for Windows, replace the 'export' with 'set'

4. Edit .env file according to the instructions. It is recommended to use wandb to manage the logs.

cp .env.example .env
vim .env

Environment Setup (After First Time)

Once all these settings are configured, the next time you simply need to execute these code snippets to set up the environment

source /root/miniconda3/etc/profile.d/conda.sh
conda activate DTT

Inference

1. Download checkpoints from either:
   • https://mega.nz/folder/E4c1QD7Z#OkgM_dEK1tC5MzpqEBuxvQ
   • https://pan.baidu.com/s/1Tw6Fp6wYVZTqjRE-aDZdyw (code: lgwe)
2. Run code

python run_infer.py model=vocals ckpt_path=xxxxx mixture_path=xxxx

The files will be saved under the folder PROJECT_ROOT\infer\songname_suffix\

Parameter Options:

• model=vocals, model=bass, model=drums, model=other

Evaluation

Change pool_workers in configs\evaluation. You can set the number as the number of cores in your CPU.

export ckpt_path=xxx # for Windows, replace the 'export' with 'set'

python run_eval.py model=vocals logger.wandb.name=xxxx

# or if you don't want to use logger
python run_eval.py model=vocals logger=[]

The result will be saved as eval.csv under the folder LOG_DIR\basename(ckpt_path)_suffix

Parameter Options:

• model=vocals, model=bass, model=drums, model=other

Train

Note that you will need:

• 1 TB disk space for data augmentation.
  • Otherwise, edit configs/datamodule/musdb18_hq.yaml so that:
  • aug_params=[]. This will train the model without data augmentation.
• 2 A40 (48GB). Or equivalently, 4 RTX 3090 (24 GB).
  • Otherwise, edit configs/experiment/vocals_dis.yaml so that：
  • datamodule.batch_size is smaller
  • trainer.devices:1
  • model.bn_norm: BN
  • deletetrainer.sync_batchnorm

1. Data Partition

python demos/split_dataset.py # data partition

2. Data Augmentation (Optional)

# install aug tools
sudo apt-get update
sudo apt-get install soundstretch

mkdir /root/autodl-tmp/tmp

# perform augumentation
python src/utils/data_augmentation.py --data_dir /root/autodl-tmp/musdb18hq/

3. Run code

python train.py experiment=vocals_dis datamodule=musdb_dev14 trainer=default

# or if you don't want to use logger

python train.py experiment=vocals_dis datamodule=musdb_dev14 trainer=default logger=[]

The 5 best models will be saved under LOG_DIR\dtt_vocals_suffix\checkpoints

4. Pick the best model

# edit api_key and path
python src/utils/pick_best.py
