ADPCM

Implements an ADPCM coder for waveform coding of speech

You are now following this Submission

Speech processing designates a team consisting of Prof. Lawrence Rabiner (Rutgers University and University of California, Santa Barbara), Prof. Ronald Schafer (Stanford University), Kirty Vedula and Siva Yedithi (Rutgers University). This exercise is one of a set of speech processing exercises that are intended to supplement the teaching material in the textbook “Theory and Applications of Digital Speech Processing” by L R Rabiner and R W Schafer.
This MATLAB exercise implements an Adaptive Differential Pulse Code Modulation (ADPCM) coder for waveform coding of speech signals.
