This G.722 speech codec conforms to ITU-T G.722
recommendation that specifies speech compression and decompression at rates of 48, 56, or 64 Kbps based on Sub- Band Adaptive Differential Pulse Code Modulation (SB-ADPCM). G.722 SBADPCM encoder reduces a bit rate of a uniform digital signal, which is coded using 14-bit with 16 kHz sampling, to 64 kbps (or 56 or 48 kbps). G.722 decoder performs the reverse operation to the encoder. It can be effectively used for audio and speech compression in speech storing, digital circuit multiplication and telephony applications....view full
