G.723.1 Audio codec source code(C/C++)

G.723.1 Audio codec source code(C/C++). EasyG723.1 is an implementation of ITU G.723.1. EasyG723.1 support multiple channels concurrent. There is no limit in concurrent channels and it can up to thousands channels. EasyG723.1 is a 6.3kbps/5.3kbps coder that encodes/decodes speech signal. The coder operates on speech frames of 30 ms, corresponding to 240 samples at a sampling rate of 8000samples/sec. In addition to the 30 ms speech frame duration, there is also a look-ahead delay of 7.5 ms, resulting in a total initial algorithmic delay of 37.5ms. EasyG723.1 has a binary release version on Windows and Linux. The source code of EasyG723.1 is written by C/C++, so you can easily port it to UNIX, PPC,DSP, Vxworks or other operation system that support C/C++.
