• Dependencies
• Data Generation
• Network Training
• Results Computation

Dependencies

Tensorflow (>2.11), librosa, pretty_midi, os, numpy, essentia, frechet_audio_distance

Data generation

The model is trained using the StarNet dataset, freely available on Zenodo link

Network training

• audio_utils.py --> contains shared audio utilities and functions
• params.py --> Contains parameters shared along scripts
• network_lib_attention.py --> Contains Denoising Diffusion Implicit Model Implementation
• DiffTransfer.py --> Actually runs the training, takes the following arguments:
  • dataset_train_path: String, path to training data
  • desired_instrument: String, name of desired output instrument
  • conditioning_instrument: String, name of input instrument
  • GPU: number of GPU, in case you have multiple ones

Results computation

• compute_eval_tracks_mixture.py
• compute_eval_tracks_separate.py
• compute_frechet.py
• compute_jaccard.py
• compute_listening_test_results.py
• preprocess_tracks_listening_test.py
