Description copied from class: SignalProcessor

This function should be overwritten by all classes that want to modify an PCM audio stream. The audio data is uniform and interleaved. uniform: Each sample has a value between -1.0 and 1.0 interleaved: The channels are not separated. They are bundled in frames e.g. if there is stereo PCM data: data[0] and data[1] are the left and right channels of sample 0 data[2] and data[3] are the left and right channels of sample 1 data[4] and data[5] are the left and right channels of sample 2 and so on ... The number of samples can be calculated by: frames * channels

Overrides:

modify in class SignalProcessor

Parameters:

data - the audio data

samples - the number of sample frames contained in "data"

channels - number of channels

rate - the sample rate
