AssumeSampleRate

AssumeSampleRate(clip clip, int samplerate)

Changes the sample rate of the current clip without changing the number of samples.

This changes the pitch, playback speed and running time of the audio.

It will also affect synchronization with the video.

Examples

# Let's say that this video is 25fps, audio 44100hz.
AviSource("video_audio.avi")

# Play video at half speed:
AssumeFPS(FrameRate/2)

# Play audio at half speed:
AssumeSampleRate(AudioRate/2)  

# Video and audio are now in sync.

If true, the audio sample rate is changed by the same amount; the pitch of the resulting audio is shifted.

If false (the default), the audio is unchanged; this means the audio will lose synchronization over time.
