Who can tell me what “kAudioQueueProperty_TimePitchAlgorithm” means in detail?
When I use audioqueue for fast forward or fast backward, I find that the speed between 0.9 and 1.25 is invalid when I do not set the property kAudioQueueProperty_TimePitchAlgorithm.
propValue = 1;
AudioQueueSetProperty(audioQueueRef,kAudioQueueProperty_TimePitchBypass, &propValue, sizeof(propValue));
propValue = kAudioQueueTimePitchAlgorithm_Spectral;
AudioQueueSetProperty(audioQueueRef, kAudioQueueProperty_TimePitchAlgorithm, &propValue, sizeof(propValue));
When I set the property kAudioQueueProperty_TimePitchAlgorithm, the speed between 0.9 and 1.25 takes effect.
