SPIRIT G.728 conforms to ITU-T G.728, G.728 Annex G, G.728 Annex I
recommendations that specifies speech compression and decompression at
rate of 16 Kbps, based on Low Delay Code Excited Linear Prediction
(LDCELP). It can be effectively used for audio and speech compression in
such applications as speech storage and voice communications.
Features
Fully bit exact with ITU-T G.728, G.728 Annex G
Sample-by-sample or block based analog input
16 Kbps bit stream rate
0.625 ms frame size
0.625 ms algorithmic delay
Direct interface with PCM 8KHz sampled data. Both sample-by-sample and block based processing supported
Simple and flexible 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
