SPIRIT G.729.1 is an 8-32 kbps scalable wideband speech and audio codec
interoperable with G.729, G.729A and G.729B.
The output of the G.729.1 coder has a bandwidth of 50-4000 Hz at 8 and 12
kbps and 50-7000 Hz from 14 to 32 kbps.
The G.729EV coder is built upon a three-stage structure: embedded Code-
Excited Linear-Prediction (CELP) coding, Time-Domain Bandwidth Extension
(TDBWE) and predictive transform coding that will be referred to as Time-
Domain Aliasing Cancellation (TDAC).
Features
Fully bit exact with ITU-T G.729.1 Recommendation
Supports wideband (50-7000 Hz)
Supports digital signal sampled at 16 kHz and 8kHz
