[Speex-dev] Issue with Wideband mode for qualities higher than 5

Merry Christmas and happy new year for everyone.
I've started porting Speex 1.2rc1 on a 32-bit microcontroller, so far
everything goes fine for Norrowband modes.
But when I'm trying to encode in wideband mode with quality higher than 5
my file back, I get inaudible "thing" (just strong noise).
- All frames are decoded with correct result (decoder function returns 0
for each decoded frame), so I
guess encoded frames are correct.
- Starting from quality 5 a low noise becomes audible and gets higher when
quality is increased
till reaching Quality 8 where I can hear nothing but annoying noise
- When I decode a file encoded on my PC (using speex utility with the same
config of my
encoder) it sounds great. So I suppose the issue might be on my
- I'm using fixed point configuration, and I updated the
to 80 (I guess I'd never outpass this value, right? but I checked
even with 200).
Is there something I should specially take care of for Wideband mode?
Did anyone encountered a similar issue?
Thank you in advance for any comments/hints :-)
With best regards.
