SPIRIT G.729AB vocoder conforms to ITU-T G.729 Annex A & Annex B
recommendation and can be effectively used in a wide range of applications for
simultaneous voice and data transmission, especially in telephony over packet
networks.
Features
Fully bit exact with ITU-T G.729 AB
8 Kbps encoded bit stream rate
Discontinuous transmission support (DTX) using Voice Activity Detection (VAD) and Comfort Noise Generation (CNG)
Direct interface with PCM 8KHz sampled data. Block based processing supported
Very simple application interface
Compliant with TI's eXpressDSP standard. Code is reentrant, supports multithreading and dynamic memory allocation. At the same time allows direct (non-eXpressDSP) interface to enable static memory allocation
Benefits
Highly optimized code ideal for resource constrained applications
