The DVI Audio compression using ADPCM (ADPCM) algorithm was first described in an IMA recommendation on audio formats and conversion practices. ADPCM is a transformation that encodes 16-bit audio as 4 bits (a 4:1 compression ratio). In order to achieve this level of compression, the algorithm

ADPCM (Adaptive Differential Pulse Code Modulation) i. Compression is possible only because sound and thus audio samples tend to have redundancies. Disadvantages of DPCM: ii. In DPCM we subtract adjacent samples and code the differences, however this method is inefficient since they do not adapt themselves to varying magnitudes of audio stream.

Other ADPCM audio compression schemes include the CCITT Recommendation G.721 (32 kilobits per second compressed data rate) and Recommendation G.723 (24 kilobits per second compressed data rate) standards and the compact disc interactive audio compression algorithm.[7,8] The IMA ADPCM Algorithm. The IMA is a consor-
