The F-scale is linear because the resolution of the analyser is
independent of frequency. It provides as much 'detail' between
10.1 and 10.2 kHz as it does between 100 and 200 Hz. Using a log
scale would mean that most of that information is thrown away.

It hasn't been for the last 10 years, and that is likely to
stay that way. For the type of measurements that JAAA is
designed for a log scale wouldn't make much sense.

The only type of measurement that is usually presented with
a log frequency scale is the traditional 'frequency response',
plot and Jaaa isn't the right tool to create that.



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
