Speex dev - May 2007 - problem on blackfin

Hello,

I'm using speex provided with the Blackfin SDK on a BF533 EZ-KIT LITE

In this version of speex, the program is used in wide band with a sampling
rate of 16KHZ
But i want to use it in narrow band mode with a sampling rate of 8KHZ

In AudDriverFuncs_AD1836.c file, i see that the supported sample rate are
48000, 24000 and 16000 --> I don't understand because in the readme file
it
talks about 8000,16000 and 32000 (Is there a problem???)
Anyway i decide to add a new supported sample rate --> 8KHz

But to every sample rate there is a value associated ADC3?
I don't understand the fonction of ADC3 and the value i must fix my ADC3

So If somebody can help me please

Thanks

Damien

Hi Damien,

Sounds like your problem has more to do with the Blackfin than with
Speex. I'd say you'd probably have better luck posting on a Blackfin
forum.
