SAMPLE RATE CONVERTER AND METHOD TO PERFORM SAMPLE RATE CONVERSION

Embodiments of a sample rate converter and method for sample rate conversion are generally described herein. In some embodiments, an interpolation module calculates new digital samples for insertion into a digital sample ring, a cache module provides input digital samples of a digital sample stream to the interpolation module, and a control module maintains and provides state information to the interpolation module and the cache module. Based on pitch parameters, the control module provides the interpolation module a fractional portion of an address for use in calculating the new digital samples and provides the cache module with an integer portion of the address and an address increment.
