Android Question Visual display of the sound sample

[Lakhtin_V]

What methods exist for comparing and displaying a sound sample with reference to the timeline? Are there ready-made libraries and an example?

May use klaus's xChart to display the sound sample signal with 1.0/samplerate as timeline for x axis.

I would suggest to use the xGraph library.
It ts intended to display data versus time.
The curves are saved in a two dimensional array.
This allows to make calculations between curves and save the result in another curve.
