Q. What is “EQ”? What is it used for in Apple's GarageBand?
A. EQ is short for Equalization. Sound is made up of many frequencies from very low to very high. An EQ is like a volume control for different frequencies. For example, if the overall volume of a GarageBand project is good, but there is too much Bass, an EQ can reduce some of the Bass without affecting the higher frequencies (this is over simplified, but it should be good enough to get you going).
GarageBand from Apple Computer uses audio loops and MIDI loops in Apple Loops format. It can work with Audio Units plug-ins. Apple Macintosh Compatible FireWire and USB interfaces can be used to connect Audio and MIDI instruments to your Mac, and be recorded into GarageBand.
