nope, it was a lost comment :) ... removed

I switch volume treshold to per thousands. It maybe help you, I hope. I dont
see what I can do more, except switch to per ten thousands or more :P
"Components threshold" is a bit difficult to explain without explain the whole
note recognition algorithm. I will document all theses things on the website
of my other project
'Free Audio Note Recognition' (http://home.gna.org/fanr)
the algo is not completely finished, so I'll not comment this immediatly, but
I'll do it ... one day ;) leave it as it is. (In your case of db treshold, it
wont help you).

I got this bug too, but now, it disapears, tell me if you can get it back with
the next version.
'enable-gui' was an example !
I modified the INSTALL file, the '$make configure' command interface and the
developer-doc page on the website, I hope it's clearer.
Thanks for your interest in this project,
Best regards,
Gilles
