java G711 编码
This Java code implements G.711 A-law compression and decompression. The `CMG711` class contains `aLawCompressTable` and `aLawDecompressTable`, arrays used for efficient encoding and decoding of audio data using the A-law algorithm. The `cClip` constant defines a clipping value for signal processing. This code provides a practical implementation of the G.711 A-law standard within a Java environment.
