Interface AudioStretcher

All Known Implementing Classes:

CutAudioStretcher, DefaultAudioStretcher, InsertAudioStretcher, PassThroughAudioStretcher

public interface AudioStretcher

An AudioStretcher will change audio samples duration, in response to a TimeInterpolator that altered the sample timestamp. This can mean either shrink the sample (in case of video speed up) or elongate it (in case of video slow down) so that it matches the output size.

Method Detail

stretch

void stretch(@NonNull
             java.nio.ShortBuffer input,
             @NonNull
             java.nio.ShortBuffer output,
             int channels)

Stretches the input into the output, based on the Buffer.remaining() value of both. At the end of this method, the Buffer.position() of both should be equal to their respective Buffer.limit(). And of course, both Buffer.limit()s should remain unchanged.

Parameters:

input - input buffer

output - output buffer

channels - audio channels
