G.723.1 Audio codec 64bits Source code. 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++. This version has no time limitation.
