(wip) TCC - Modulation Spectrogram Transform

How this repository is organized:

  • poc/ : Holds Jupyter Notebooks sandboxes
  • lib/: Implementation. Basically taking what works from poc/ and making a package of it.
  • samples/: Short audio samples.

How to run it:

There's a requirements.txt file with all the used packages. I recommend using venv to open it. You can follow the instructions here.
