Detecting the pitch of an AudioBuffer? Without playing the audio back.

Would it be possible to use this library to detect a pitch of Wav samples, decoded audio buffers, without actually playing the audio? Thank you!

You can actually use the AudioBuffer class. It has a getChannelData() function that returns a Float32Array of samples from the specified channel. That array will contain the whole AudioBuffer data from the specified channel (with values ranging from -1 to 1), which in turn you can use with the auto-correlation function. :)
