This project explores using KSVD to transcribe piano music in the time domain. See the paper in the paper directory for full details.
The MAESTRO dataset is available here to get the training data. The code is located in the jupyter notebook KSVD.ipynb. The code is written in Julia and is pretty straightforward. One hiccup is that the code uses librosa (from Python) via pyimport. In order to do this, the LLVM versions of python and Julia must match. Using Python 3.7.1 and Julia 1.4 dev this works fine.
