How to get echo tone? #2

Closed weathon closed 5 years ago

weathon commented 5 years ago

I have read the document, but I still don't know how to get echo tone, like the demo app https://killercrush.github.io/music-tempo/example/example-advanced.html It can get every tone note and their loudness, time and frequency.

I meanhow to get the Spectrogram

killercrush commented 5 years ago

This library is intended only to determine the tempo of music. In the demo app I used java-library TarsosDSP to calculate the spectrogram (Constant Q). To convert java to javascript I used JSweet.
