News!

2021-10-29 update matlab feature (key, tempo, note density)

2021-07-21 update dataset

2021-07-20 Upload all pretrained weight

you can check ML performance in notebook

1. Install python and PyTorch:

   • python==3.8.5
   • torch==1.8.0 (Please install it according to your CUDA version.)

2. Other requirements:

   • pip install -r requirements.txt

3. git clone MIDI processor (already done)

   • MIDI-like(magenta)
   • REMI
   • If you want to bulid new REMI corpus, vocab from other dataset, plz check official repo of compund-word-transfomer and EMOPIA_cls/midi_cls/midi_helper/remi/src

download model weight in Here, unzip in project dir.

1. MIDI domain inference

    python inference.py --types {midi_like or remi} --task ar_va --file_path {your_midi} --cuda {cuda}
    python inference.py --types {midi_like or remi} --task arousal --file_path {your_midi} --cuda {cuda}
    python inference.py --types {midi_like or remi} --task valence --file_path {your_midi} --cuda {cuda}
   

2. Audio domain inference

    python inference.py --types wav --task ar_va --file_path {your_mp3} --cuda {cuda}
    python inference.py --types wav --task arousal --file_path {your_mp3} --cuda {cuda}
    python inference.py --types wav --task valence --file_path {your_mp3} --cuda {cuda}
   

    python inference.py --types wav --task ar_va --file_path ./dataset/sample_data/Sakamoto_MerryChristmasMr_Lawrence.mp3

    ./dataset/sample_data/Sakamoto_MerryChristmasMr_Lawrence.mp3  is emotion Q3
    Inference values:  [0.33273646 0.17223473 0.63210356 0.07314324]

    python inference.py --types midi_like --task ar_va --file_path ./dataset/sample_data/Sakamoto_MerryChristmasMr_Lawrence.mid

    ./dataset/sample_data/Sakamoto_MerryChristmasMr_Lawrence.mid  is emotion Q3
    Inference values:  [-1.3685153 -1.3001229  2.2495744 -0.873877 ]

1. Download the data files from HERE.

2. Preprocessing

   a. audio: resampling to 22050

   b. midi: magenta feature extraction, remi feature extraction

    python preprocessing.py
   

3. training options:

   a. MIDI domain classification

    cd midi_cls
    python train_test.py --midi {midi_like or remi} --task ar_va
    python train_test.py --midi {midi_like or remi} --task arousal
    python train_test.py --midi {midi_like or remi} --task valence
   

   b. Wav domain clasfficiation

    cd audio_cls
    python train_test.py --wav sr22k --task ar_va
    python train_test.py --wav sr22k --task arousal
    python train_test.py --wav sr22k --task valence
