Speex modes
...MacOS X and Windows).. As it is now the user can set complexity
(SPEEX_SET_COMPLEXITY) and quality (SPEEX_SET_QUALITY /
SPEEX_SET_VBR_QUALITY) and to wether to use VBR or not. Will these
options
make it possible to produce all combinations of bitrates/qualities? Or
should I also use SPEEX_SET_MODE/SPEEX_SET_LOW_MODE/SPEEX_SET_HIGH_MODE
to
accomplish this?

About wideband encode
Hi, all.
I have two questions about wideband encoding.
>From "testenc_wb.c"...
1)
tmp=8;
speex_encoder_ctl(st, SPEEX_SET_QUALITY, &tmp);
tmp=3;
speex_encoder_ctl(st, SPEEX_SET_HIGH_MODE, &tmp);
tmp=6;
speex_encoder_ctl(st, SPEEX_SET_LOW_MODE, &tmp);
How to set high_mode and low_mode, if quality is set to '9'?
When I set quality '9' / high_mode '3' / low_mode '6', encode as like quality is '8'.
And what does high/low mode value in encoding process?
2)

The first thing to know that setting quality from 0-10 is in fact a more
user-friendly of setting the mode. That being said, for narrowband
encoding, all modes are available with at least one quality setting
(sometimes two quality settings point t...
