Abstract
A method for providing audio sample rate conversion within a data-processing system is disclosed. An audio data stream is first received. If the input sample rate of the audio data stream is not equal to a target sample rate, several frequency multiplications or frequency divisions are selectively performed until the target sample rate is reached. Then, the audio data stream is passed through a lowpass filter having a cutoff frequency that is less than half of the target sample rate. Finally, the audio data stream is output.
