Hi all, I'm developing with TMS320C5416 DSP and TLV320AIC12 codec. 16 bits samples at 8000 Hz sampling frecuency, are received into a buffer. When this buffer is full,I code it through G.729 ITU codec and then I decode it. But, when I write the decoded buffer into the output device, I hear a loud background noise. G729 codec needs 16 bits, 8000Hz, PCM to work. TLV320AIC12 is configured to work with 16 bits samples, 8000 Hz and continuos mode. Can anybody help me? Thanks!! |

I have the same problem. I'm implementing G.729 Annex D ITU codec and when I write the decoded buffer into the output device, I hear a noise which sounds like a machine gun. Can anyone help us thanks in advance |
