Musdb model

[hayduck]

Hello,

I'm trying to use predict to improve some old music have, as was done here in your project:

Section Ⅴ: Examples for samples upsampled from 11.025kHz to 44.1kHz.
The model is trained on the train set of the MusDB-HQ dataset.

but I think I need a msudb experiment yaml file. I was able to download the checkpoint.tf, and tried to use the output naming convention to predict, but there is not a matching experiment yaml file I believe. The dset training hydra config would be nice too if possible.

Thanks much, and cool project.

If the experiment config is the same as the others, with just different input and output frequencies, im happy to give that a shot and make a pr, I just have no idea if there are other changes.

Same here. Looking for the music upscaling model

Hello, I would also be interested in running the model trained on music data. Are there any updates on this?

@hayduck @yihaoch @pf-mpa, the author did answer this question in another issue: #5 (comment)

They created a musdb-mixture-11-44.yaml file in the dset folder for musdb containing the following:

# @package dset
name: musdb-mixture-11-44
train: egs/musdb18hq/11025-44100_mixture/tr
valid: egs/musdb18hq/11025-44100_mixture/val
test: egs/musdb18hq/11025-44100_mixture/val

It doesn't look like they used an experiment file directly, they instead specified the options as command line arguments like this:

python train.py \
  dset=musdb-mixture-11-44 \
  experiment=<experiment_name> \
  experiment.nfft=512 \
  experiment.hop_length=64 \
  experiment.lr_sr=11025 \
  experiment.hr_sr=44100 \
  epochs=696 \
  eval_every=175 \
  losses=[stft] \
  experiment.batch_size=16 \
  cross_valid_every=5 \
  wandb.resume=false \
  experiment.aero.spec_upsample=true \
  experiment.upsample=false \
  experiment.aero.enc_freq_attn=0 \
  experiment.aero.norm_starts=2 \
  experiment.aero.dconv_time_attn=2 \
  experiment.aero.dconv_lstm=2 \
  experiment.aero.freq_ends=4 \
  experiment.aero.strides=[4,4,2,2] \
  experiment.aero.channels=48 \
  experiment.melgan_discriminator.ndf=16 \
  +experiment.speech_mode=false \
  cross_valid=false \
  joint_evaluate_and_enhance=true \
  ddp=true \
  visqol=false \

note: I am yet not sure if <experiment_name> is the file name of a yaml expertiment config that is being overwritten, or the name: value for the experiment.

I'm currently training another model, but I'll make a pr of a yaml file containing those experiment options when I get around to trying this again.
It would be interesting to upgrade the hdemucs model used by aero to the newest htdemucs which has a far better SDR.

Training Hint: Consider augmenting your MUSDB18 dataset before running the areo resample.py data preparation script.
Useful tools:

• demucs automix.py (requires local demucs install with pip install -e .) creates musically plausible mashups
• spotify pedalboard can be used for "on-the-fly" augmentations during training: example: augm_data() function
• audiomentations can also be used for "on-the-fly" audio augmentations (see previous augm_data() example)
