I've just been using this to do some tests on an Amp and it's produced some
interesting and useful results. However, I would really like a log frequency
scale.
Is this a practical future option?
I'm using V 0.8.4 which comes with debian testing.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

Have you tried japa by the same author? It has a log frequency scale,
although I don't know how it stacks up feature-wise.

The only chance for jaaa to win against japa feature-wise is when you
want less features to win...

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.

Japa will show them.
Connect
Japa:pink_noise -> EQ:in
EQ:out -> Japa:in-1
Japa:pink_noise -> Japa:in-2
Select input 1 on A, input 2 on B, slow respose, and
display A/B.
