A 'perfect' iTunes equalizer setting
Authored by: BarracksSi on Sep 03, '04 10:08:22AM

If all you want to do is equalize away the inherent problem resonances in your speakers, you can do it by hand.

Make a sound file in Audacity with about a second's worth of sine wave for each iTunes EQ band. Save it as an AIFF file, import it into iTunes (still as AIFF, not mp3 or AAC), set playback to repeat, and hit Play.

Open up the EQ window, and reduce the sliders where you hear peaks in the sound. Don't boost anything -- you'll greatly increase the risk of distortion. If you're setting this up for your laptop, cut the bass as well, because those tiny speakers can't afford to be overworked trying to play frequencies that sound best through subs 8" or larger.

You can set up different EQ curves for the speakers you have on your desktop, your headphones & earphones, and anything else. Unfortunately, I haven't found a way to export the settings to my iPod (I've read EVERYTHING posted so far, and nothing works).

My iBook-specific EQ has these cuts: 32 Hz -9dB; 64 Hz -3; 500 Hz -9; 4 KHz -5; 8 KHz -3; 16 KHz -1. Another curve, for my Apple earbuds, came out like this: 2 KHz -2; 4 KHz -6; 8 KHz -4.

VolumeLogic does work extremely well, but with music containing a wide dynamic range (large-scale symphonic stuff, for example), the softs are louder than they should be. But, for general listening, [i]especially[/i] on tiny underpowered speakers like those on your laptop, it's very, very good.

easier than creating a sound file in Audacity is to use the free program PerfectTone:

type in a starting frequency, then "shft <" or "shft >" to sweep the audio spectrum .
