This is the code accompayning TriAD: Capturing harmonics with 3D convolutions. It is mostly based on Jong Wook's repository.
You need to get two datasets: Maestro and Maps. Maestro is hosted in Google's servers, and you can download it and
parse it using the prepare_maestro.sh script.
When calling the script, use -s to indicate where will be Maestro downloaded; a symbolic link data/MAESTRO will be
created pointing at the location where maestro was downloaded & unzipped.
It will also take care resampling and encoding the files as FLAC.
In case you have Maestro already in your computer, you can just use the bash script in Jong Wook's repository.
To obtain the MAPS dataset just download it from Jong Wook's repository, and place it in data/MAPS
All package requirements are contained in requirements.txt. To train the model, run:
pip install -r requirements.txt
python train.pytrain.py is written using sacred, and accepts configuration options such as:
python train.py with logdir=runs/model iterations=1000000Trained models will be saved in the specified logdir, otherwise at a timestamped directory under runs/.
To evaluate the trained model using the MAPS database, run the following command to calculate the note and frame metrics:
python evaluate.py <path/to/your/saved/model>Specifying --save-path will output the transcribed MIDI file along with the piano roll images:
python evaluate.py <path/to/your/saved/model> --save-path output/In order to test on the Maestro dataset's test split instead of the MAPS database, run:
python evaluate.py <path/to/your/saved/model> MAESTRO testPlease, if you use this repository or the model consider citing:
