Description: G721-G723 源代码
G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.-G721-G723 source code of G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s.

of the CCITT (International Telegraph and Telephone Consultative Committee)
G.711, G.721 and G.723 voice compressions. They have been tested on Sun
SPARCstations and passed 82 out of 84 test vectors published by CCITT
(Dec. 20, 1988) for G.721 and G.723. [The two remaining test vectors,
which the G.721 decoder implementation for u-law samples did not pass,
may be in error because they are identical to two other vectors for G.723_40.]

Description: The primary purpose of this book is to explain various data-compression techniques using the C
programming language. Data compression seeks to reduce the number of bits used to store or transmit information. It encompasses a wide variety of software and hardware compression
techniques which can be so unlike one another that they have little in common except that they
compress data. The LZW algorithm used in the Compuserve GIF specification, for example, has
virtually nothing in common with the CCITT G.721 specification used to compress digitized voice
over phone lines.
