Abstract: A de-shuffling circuit of a first audio processor 21 performs the following signal processing. When an audio signal is to be reproduced from a video tape 1 in which an audio signal having 4004 samples in consecutive 5 fields is recorded on a helical track, with the number of effective samples for one field equal to 800 or 801, all samples of at least one reproduction among audio signals produced by two or more reproductions of an image signal of the same field are outputted and samples of other reproductions are adaptively controlled in a variable speed reproduction mode for reproducing an arbitrary field twice or more with a dynamic tracking head 2A. Thus, the total number of samples for the 5 fields is limited to not more than 4004.

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.
