a speech signal that were sampled at 2 KHz and 44 KHz, respectively. The source code file of the MATLAB code and the output can be viewed using MATLAB. Differential Pulse Code Modulation (DPCM) In PCM, each sample of the waveform is encoded independently of all the other samples.

Differential pulse code modulation is a derivative of the standard PULSE CODE MODULATION. It uses the fact that the range of differences in amplitudes between successive samples of the audio waveform is less than the range of the actual sample amplitudes 6. In analog messages we can make a good guess about a sample value from a knowledge of the ...

DPCM (Differential Pulse Code Modulation) i. Adjacent audio samples tend to be similar in much the same way that neighboring pixels in an image tend to have similar colours. ii. The simplest way to exploit this redundancy is to subtract adjacent samples and code the differences, which tend to be small integers. Any audio compression method on this principle is called DPCM. iii.

Adaptive Differential Pulse Code Modulation is the algorithm we used for compressing audio data. The ADPCM takes advantage of correlation between consecutive audio samples. While ADPCM is mostly intended for speech samples, it still …
