[opus] Q: Bandwidth vs. bitrate

Hi Ulrich,

I assume you've been using opusenc to encode the files. If that is the
case you can try giving the encoder some more hints about your files:

opusenc --speech --set-ctl-int 4008=1103 ...

The latter should tell the encoder that the signal bandwidth is 8kHz
(OPUS_SET_BANDWIDTH). See opus_defines.h for all valid numbers. You can
also experiment with the complexity settings.
