|Improvement to ATRAC which allows a more flexible interpretation of "minimum limit of audibility" depending upon the signal characteristics.
|The method of encoding digital data in the present invention enables change of minimum limit of audibility characteristics and/or masking characteristics, which are usually set on the basis of the aural-psychological characteristics of persons with typical hearing, thus changing the allocation of quantized bits to each frequency band and allowing selection of a sound quality which accords with the listener's hearing. The present invention is suitable for ATRAC, a method for compressed encoding for mini-discs.
