Seeing as lower/higher frequencies change their impact disproportionally depending on the volume, I would like to boost lower frequencies when playing music quietly, and reduce when playing loudly. Now, this would be a very crude way to go about it, so is there any software that could do it automatically (and more importantly, more precisely) across the whole frequency range?
Preferably for foobar, but if you know of anything that can do this - I'd be interested to know.
Maybe some eq calibration software similar to what some home theathres have?
I have a decent microphone and a cheap sound level meter - am I right that the former would be more suitable for something like this? Are there any rules of thumb or a reliable method to do this manually 'by ear'?
While at it, is there anything that can switch eq/preset depending on the output device as well?
