Abstract
Techniques and mechanisms implement a sample rate converter for resampling data, such as audio data. The resampling may be based on a resampling clock. As the frequency of the resampling clock varies (e.g., due to jitter, rate adjustment, etc.), a control loop feedback mechanism can detect the variations and gradually correct the sampling rate of the resampled data.
