[speex-dev] low sampling rate for Wideband ?

[Tongbiao Li]

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,
