NettetThe G.723-1 system encodes the audio signal in frames using linear predictive analysis-by-synthesis coding. The coder uses a limited amount of complexity to represent speech at high quality. The G.723-1 coder has two associated bit rates—5.3 and 6.3 kbits per second. Although both bit rates pr ovide good audio reproduction quality, NettetIntroduction. In this example you implement LPC analysis and synthesis (LPC coding) of a speech signal. This process consists of two steps: analysis and synthesis. In the analysis section, you extract the reflection coefficients from the signal and use it to compute the residual signal. In the synthesis section, you reconstruct the signal using ...
