About this document

VTU Multimedia Communication Guide by SOUMYASAI GANESHKAR is a document available to read on EtoBox.

This document discusses audio compression techniques for multimedia communication. It describes how audio signals are digitized using pulse code modulation (PCM) and the need for compression to reduce bandwidth requirements. It then explains differential pulse code modulation (DPCM) and adaptive differential PCM (ADPCM), two common audio compression techniques. DPCM encodes differences between adjacent audio samples, while ADPCM varies the number of bits used to encode differences based on their amplitude.
