In 1973, P. Cummiskey, Nikil S. Jayant, and James L. Flanagan of Bell Labs introduced Adaptive DPCM (ADPCM). Perceptual coding was first used for linear predictive coding (LPC) speech coding compression. The original concept of LPC &hellip; Continue reading \"\"","thumbnail_url":"https:\/\/www.epiphan.com\/wp-content\/uploads\/2016\/06\/Audio-encoding_audio-codecs_illus.gif"}
