ADPCM stands for Adaptive Differential Pulsation Code Modulation. The code Sp(k) is adjusted using the code I(k), the signal estimate Se(k), and the scale factor y(k) so that even if PCM and ADPCM links are interconnected synchronously, as in a PCM-ADPCM-PCM-ADPCM interconnection, no more degradation occurs than would occur in the first-stage PCM-ADPCM-PCM interconnection; then the code Sp(k) is converted to. Further, we down loaded the kernel code of ADPCM and CELP algorithms (in C language) from the web [6]. 721), can be achieved with a single TMS32010. Unfortunately, several distinct encoding systems exist for traditional multimedia content. Codecs based on adaptive differential pulse code modulation (ADPCM), as analyzed in [8, 9, 10], cause a single sample delay which would be optimal for delay-sensitive applications but are ranked.

If the difference signal is low, ADPCM increases the size of the quantization levels. The adaptive quantizer codes d(n) into codeword c(n) which is sent over the transmission facility. The basic PCM technique is to use a codec (coder/decoder) to sample the amplitude of a voice signal 8,000 times per second, and then store the amplitude value as 8 bits of data. The technique converts the analog signals by taking frequent samples of the sound and representing the value of the sampled modulation in binary form. Linear Pulse Code Modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
