[speex-dev] --dtx alone does nothing?

Right now, it looks at what's the average bit-rate so far and does some
adjustments to meet the target. There might be ways to improve, it's
very rough right now. Also, note that you'll likely get better results
by trying several --quality until you get the right bit-rate than with
--abr.

--quality 8 and --bitrate 15000 are exactly equivalent. That's not the
case with --abr.

> What is the range of quality <float>?  0-10 like the int or 0.0-1.0?

0-10
