## Useage

MelMatchEQ is a profiling EQ using a 26 step Mel Frequency Band.

You could analyze the spectral profile of a sound source by press 'Match1'.
Press 'Match1' again when done.

Now you could (optional) save the profile by press 'Profile' and select 'save',
enter a name for it in up popping text input field and press 'ok'.
This way you could later reuse it to compare it with other sound sources.

After that (or after loading a profile from the menu), you could profiling 
the second sound source, the one you want to match the spectrum of the first
source by press 'Match2'. 
Press 'Match2' again when done. MelMatchEQ will calculate and apply 
the needed EQ settings to match the spectrum of the first profile.
Those EQ settings you could save as preset (host side).

That's it. 
You could save/load/delete up to 15 profiles and unlimited presets.
Surely you could set the EQ settings by hand (mouse or keyboard) at any time, 
to match the result even more to your taste.

To clear the EQ settings, press 'Clear'.
That will clear the EQ parameters, but keep the loaded profile in use.

If a profile is loaded, you could see it as little blue bar's in the EQ screen,
and the profile name is displayed above.
