- Modular functions, python based, can be easilly added ... my framework works over numbers, and numbers, and their analyse.
- The fewer external libraries and dependences used here, the better. Only chord-extractor and librosa for the audio analysing and controls. NumPy for anything numbers related. jQuery, Chart.js are also used for scripting database support.
The program generates:
