4kbps sounds robotic on TMS320C64
...neric.h change but that didn't help.

Jean-Marc,
Yes, fixed-point is enabled (#define FIXED_POINT in config.h). I haven't tried anything lower than 4kbps; like I mentioned, 6kbps sounds fine so it's very strange. The only code I changed to get 4kbps was setting quality to 1 so that is the only difference in my test code b...

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 sound...
