Tweak your sound in iTunes and on the iPod
Depending on how you listen to your music, you may want–or need–to adjust the sound that comes out of your computer or your iPod. If you have simple speakers connected to your computer, or use an iMac’s internal speakers, you might not have bass and treble adjustments available. Yet for some music, you may want to change the overall sound by increasing or decreasing certain frequencies.
Equalization is changing the volume of certain frequencies to change the sound of music during playback. iTunes includes a graphic equalizer that lets you change the volume of 10 different bands to alter your music, and, in many cases, improve the sound. To access the iTunes equalizer, press Command-Option-2, or choose Window: Equalizer. If you’re familiar with the way an equalizer works, you’ll see that the display of the Equalizer window is pretty much the same as a standalone graphic equalizer. It has sliders that let you adjust the volume of each of its 10 bands; just drag them up or down.
