G.729A is one of the reduced
complexity standards of G.729. G.729 is ITU-T speech compression algorithm
which is based on Conjugate Structured Algebraic Code Excited Linear Prediction
(CS-ACELP). The G.729A compresses 8 kHz linear audio signals and encodes them
for transmission at 8 Kbps. Input is 16 bit PCM. Input bit stream is segmented
into frames of 10ms and processed. Prediction analysis is done using a
synthesis filter of order 10.
