Abstract
A method and apparatus for adjusting a sample rate for an asynchronous sample rate converter is disclosed. In one embodiment, an apparatus includes an asynchronous sample rate converter (ASRC) that is configured to receive a digital data stream provided at a first sample rate. The ASRC is configured to convert the digital data stream to a second sample rate at which it is output. The apparatus also includes a sample rate estimator coupled to an interface through which samples from the digital data stream are conveyed subsequent to conversion to the second sample rate. The sample rate estimator is further coupled to the ASRC, and configured to adjust the second sample rate based on information obtained from the interface.
