I'm searching for an audio API to parse a .wav file and show its waveform.
Someone knows something similar?
If not, someone could tell me how to do it by myself?
I mean if I open the file .wav and get one buffer at time, what I should do
to know its waveform?
Thank you,

libsndfile seems to be the standard:

Well if you read the samples [1, 2, 3, 4, -4, -3, -2, -1] then the
waveform is something like:
