DrummerNet

This is supplementary material of "Deep Unsupervised Drum Transcription" by Keunwoo Choi and Kyunghyun Cho, ISMIR 2019 (Delft, Netherland).

Paper on arXiv | Blog post

• What we provide: Pytorch implementation for the paper
• What we do not provide:
  • pre-trained model
  • drum stems that we used for the training

Installation

If you're using conda and wanna run it DrummerNet CPU, make sure it installs mkl because we'll need its fft module.

conda install -c anaconda mkl

Then,

pip install -r requirements.txt

Using conda, it would be something like this, but customize it yourself!

conda install -c pytorch pytorch torchvision 

Python3 required.

Preparation

Wav files for Drum Synthesizer

• data_drum_sources: folder for isolated drum sources. 12 kits x 11 drum components are included. If you want to add more drum sources,

  • Add files and update globals.py accordingly.

  # These names are matched with file names in data_drum_sources
  DRUM_NAMES = ["KD_KD", "SD_SD", "HH_CHH", "HH_OHH", "HH_PHH", "TT_HIT", "TT_MHT",
                "TT_HFT", "CY_RDC", "CY_CRC", "OT_TMB"]
  N_DRUM_VSTS = 12

  • Note that as shown in inst_src_sec.get_instset_drum(), the last drum kit will be used in the test time only.

Training files

We unfortunately cannot provide the drum-stems that we used for the trained network in the paper.

• /data_drumstems: nearly blank folder, placeholder for training data. I put one wav file and files.txt as an minimum working example.
• Mark Cartwright's and Richard Vogl's papers/codes provide a way to synthesize large-scale drum stems

Evaluation files, e.g., SMT

• It is not part of the code, you have to download/process it by yourself.
• First, download SMT dataset (320.7MB)
• Unzip it. Let's call the unzipped folder PATH_UNZIP
• Then run $ python3 drummernet/eval_import_smt.py PATH_UNZIP. E.g.,

  $ cd drummernet
  $ python3 eval_import_smt.py ~/Downloads/SMT_DRUMS/
  Processing annotations...
  Processing audio file - copying it...
  all done! check out if everything's fine at data_evals/SMT_DRUMS

• data_evals: blank, placeholder for evaluation datasets

Training

• If you prepared evaluation files

python3 main.py --eval false -ld spectrum --exp_name temp_exp --metrics mae

• Otherwise,

python3 main.py --eval true -ld spectrum --exp_name temp_exp --metrics mae

If everything's fine, you'll see..

$ cd drummernet
$ python3 main.py --eval True -ld spectrum --exp_name temp_exp --metrics mae
Add arguments..
Namespace(activation='elu', batch_size=32, compare_after_hpss=False, conv_bias=False, eval=False, exp_name='temp_exp', kernel_size=3, l1_reg_lambda=0.003, learning_rate=0.0004, loss_domains=['spectrum'], metrics=['mae'], n_cqt_bins=12, n_layer_dec=6, n_layer_enc=10, n_mels=None, num_channel=50, recurrenter='three', resume=False, resume_num='', scale_r=2, source_norm='sqrsum', sparsemax_lst=64, sparsemax_type='multiply')
| With a sampling rate of 16000 Hz,
| the deepest encoded signal: 1 sample == 64 ms.
| At predicting impulses, which is done at u_conv3, 1 sample == 1 ms.
| and sparsemax_lst=64 samples at the same, at=`r` level
n_notes: 11, n_vsts:{'KD_KD': 11, 'SD_SD': 11, 'HH_CHH': 11, 'HH_OHH': 11, 'HH_PHH': 11, 'TT_HIT': 11, 'TT_MHT': 11, 'TT_HFT': 11, 'CY_RDC': 11, 'CY_CRC': 11, 'OT_TMB': 11}

then you'll see the model details.

Troubleshooting

Install MKL for pytorch FFT

In case you face this error,

RuntimeError: fft: ATen not compiled with MKL support

As stated here, this is an issue of MKL library installation. A quick solution is to use Conda. Otherwise you should install Interl MKL manually.

In some cases, if Pytorch was once built without MKL, it might not able to find later-installed MKL. You should try to remove the cache of pip/conda. Or just make a new environment.
