ABSTRACT:
An audio rate converter converts a sampling rate for audio data into a fixed rate. In the audio rate converter, an input audio data DAin at a sampling rate of PFS (48 kHz.+-.x%) are stored in the memory in accordance with a write address WAD which is synchronized with the rate PFS. Audio data are read from the memory in accordance with a read address RAD which is synchronized with a rate FS (48 kHz), and coefficient data determined based on a sampling point in output audio data are read from a ROM table in accordance with a read address Coef.AD which is synchronized with the rate FS. A data arithmetic and logic circuit performs multiplying and adding operations using these data in order to produce the output audio data DAout. If the sampling rate PFS at which the input audio data are provided changes, the audio rate converter can provide the output audio data DAout at the fixed sampling rate FS.
