Hello all, I am new to world of codec !!! :( . WE have few codecs in our VoIp application. Open source of GSM codec and G 723 (not G 723.1). Problem is that quality of G 723 is worse as compare to GSM or G 711 lot of noice is there. 1. Is G 723 is having quality problems ? 2. Higher bit rate means less processing time ....am i right ? .. G 723 is 24 kbps so it should require less processing time then GSM etc ? Please help !! vikram,
