G.723.1 Audio codec Win32 library(No time limitation). 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 8000 samples/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. The encoder requires raw 16-bit mono PCM speech data sampled at 8000 Hz as input, i.e., without any header information. For every speech frame, consisting of 240*16 bit (480 bytes) samples There is no time limitation for this library.
