Just now that forum is under hosting changing process, so in hands I have
multitone example wav file only. Sonic-visualiser shows approximately:
20 43 93 200 430 930 2K 4K9 9K3 20K
20, 200, 2K and 20K are exact values (I just remeber them :-)).

The idea (under discussing at some of russian DIY
audio forum) is to use
multitone signal, compare it before and after audio amplifier and (having
such *multiple* results for *different* amplifiers) to try get some - at
least partially useful - correlation between results and subjective
audio perceptions (in particular, "clearance" - don't know an
appropriate English term; it's about how easy different instruments can
be "separated" in brain).
I'm not sure it is a right way, but would like to take participation in
the experiment (especially with my last SE-invention :-)).
Fellows (using appropriate software analyzers under MS win) show very
clear spectrum plots for original multitone signal (ten -20db tones in
20Hz - 20KHz range). Having single-boot Linux, I'd want to get something
the same :-)
What are the frequencies (in particular the lowest ones) ?
