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.

2 f COMPRESSION PRINCIPLES Compression desirable to compress digital audio, image, and video so that their bit rates or storage requirements become manageable. We achieve data compression by exploiting two major factors: redundancy existing in digital audio, image, and video data the properties of human perception. 15.
