G.722.1 : Low-complexity coding at 24 and 32 kbit/s for hands-free operation in systems with low frame loss

Recommendation G.722.1

In force components
Number
Title Status
G.722.1 (05/05)
 
Low-complexity coding at 24 and 32 kbit/s for hands-free operation in systems with low frame loss  
This Recommendation includes a software package which contains the encoder and decoder source code and a set of associated test vectors for developers. The fixed-point code implements both the 7 kHz mode (main body) and the 14 kHz mode (Annex C). The floating point code implements only the 7 kHz mode
In force
G.722.1 (2005) Corrigendum 1 (06/08)
 
Correction of Annex B source code  
This corrigendum concerns only the software; the resulting release 2.1 had been included in the published ITU-T Recommendation G.722.1 (05/2005)
