Speex dev - Aug 2004 - low sampling rate for Wideband ?

Hello,

 

We currently have code for sampling at 8 KHz at device layer.  In order
to have minimal code change while still doing wideband I am thinking of
packing two 20 ms frames of the low band data as input to Wideband mode
for encoding.  Is this a feasible idea?

 

I actually tried it out.  Speech came out at the decoding end, but I
could occasionally hear low pitched, high frequency background noise.

 

 

Thank you,

I'm really not sure I understand what you're trying to do. Can you
explain a bit more? (BTW, if you're sampling at 8 kHz, I don't see what
you'd want to do with wideband).
