Audio Compression - AS2010377 15 15. 16. Adaptive Differential PCM • ADPCM, commonly termed as a form of compression, is a more efficient way of storing waveforms than 16-bit or 8-bit PCM. • ADPCM stores the value differences between two adjacent PCM samples and makes some assumptions that allow data reduction.

Digital audio compression allows the efficient storage and transmission of audio data [1]. One of the techniques that used in audio compression is wavelet transform, Wavelet compression is a form of predictive compression where the amount of noise in the data set can be estimated relative to the predictive function [2]. Wavelet coding
