Robust system is not that easy to write. I have edited and extracted
manually sounds where the fades goes deep under the noise but are
still audible. One has to do a frequency analysis to catch those
sounds (just like human ear does).
This is an interesting problem because you cannot edit those sounds
_manually_ with any flag-ship audio editor (such as SoundForge).
The main reason is:
You cannot hear the fades because editors don't have a software
play volume (ranging up to +64 dB, say). You would be a nut if
you would turn your hardware amplifier to maximum in order to hear
the fades -- a minor mistage and you would blow both your ears and
your speakers. Professional audio people have these same problems
because it is the professional software which are failing. Software
volume would be a great tool (no patent pending).
Hopefully editor authors are listening this time... I need this tool
in any editor I decide to use: Sweep? Ecawave? Snd? Glame?

Could somebody check what GPLed frequency analysis codes (easily reusable)
we have available? Both analysis-only and bandsplitting (such as phase
vocoder). Thanks. Could it be worth of combining various codes to
one library?
Best regards,
Juhana
