When the input and the output clocks are asynchronous, the nearest interpolated value can be used to approximate the desired output sample. The design for an asynchronous sample rate conversion (ASRC) from 44.1kHz compact disk to 48kHz digital audio tape is presented. Using wave digital filter and a fractional delay filter, the ASRC is implemented in all-digital form. To this end, this paper proposes a novel IIR fractional delay filter. Compared with other methods, the proposed method requires less hardware complexity and obtains signal-quality compatible with digital audio.
