WebG.729 specifies a coding scheme that compresses 64-KBPS PCM speech to 8-KBPS using a conjugate structure algebraic-code- excited linear-prediction (CS-ACELP) algorithm. The coder is designed to process frames of 80 samples, or 10-milliseconds of speech data. A 5-millisecond “look ahead” is required, so the total delay is 15-milliseconds. http://noesis-tech.com/specification/cs-acelp-8-kbps-codec-ntg729/
