Abstract

See full text

An audio signal editing method and apparatus for use with original sound data which is already compressed and encoded in predictive form, for example ADPCM. To edit a desired portion from the original audio data, the method and apparatus reconstruct (encoded PCM) audio data from the original (ADPCM) audio data and encode a non-predictive unit to replace a first original audio data unit of the desired portion. Thus, the desired portion is rendered independent of preceding sample values, without having to be recoded entirely. An enhanced method and apparatus encode further replacement units to eliminate noise introduced by the basic method.
