4kbps sounds robotic on TMS320C64
Hi,
I'm currently working on the TI DaVinci processor, which has an ARM926 processor and a TMS320C64+ DSP in it. I have been using Speex 6kbps (narrowband, quality=2, complexity=1, perceptual_enh=0) on the DSP C64+ side without any issues; the voice sounds very good for such a low bandwidth requirement. However, recently, I tried out the 4kbps mode (changing quality to 1) on the DSP and it sounds robotic; if I ported the same 4kbps code to use on the ARM926 (GPP) side of the DaVinci, it so...
