audio compression: -law and adaptive differential pulse code modulation. In the following section, the paper gives an overview of a third, much more so-phisticated, compression audio algorithm from the Motion Picture Experts Group. The topics covered in this section are quite complex and are intended for the reader who is familiar with digital signal

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. iii.

processor or a specialized audio chip. Now, using a simplified Adaptive Differential Pulse Code Modulation (ADPCM) algorithm, these audio capabilities can be added to any PICmicro device. This application note will cover the ADPCM compression and decompression algorithms, performance comparison of all PICmicro

Adaptive Differential PCM Audio Compression - AS2010377 17 • An ADPCM algorithm is used to map a series of 8 bit µ-law (or a-law) PCM samples into a series of 4 bit ADPCM samples. In this way, the capacity of the line is doubled. • Some ADPCM techniques are used in Voice over IP communications.

The compression techniques used in ACT are discrete wavelet transform (DWT), adaptive differential pulse code modulation (ADPCM) and run-length coding (RLC). This technique first transforms data from time domain to frequency domain; next, it uses ADPCM to reduce the magnitude of data; consequently, it reduces the number of packets by means of RLC before …
