Adjusting audio frequencies

You can use the equalizer to change the levels of individual audio frequencies in a song. This lets you customize playback for different musical genres, listening environments, or output methods (such as speakers), to suit your musical preferences.

Click the Equalizer button on the bottom-right side of the iTunes window, then drag the sliders up or down to increase or decrease the volume (in decibels) for each frequency you want to change.

iTunes also comes with over 20 equalizer presets, designed for a wide range of types of music. To use a preset, choose it from the pop-up menu in the Equalizer window.

The equalizer's settings are applied to the currently playing songs, but you can also assign presets to specific songs in your library. For more information, click "Tell me more."
