15.2. Recording Sound

If you hope to record new sounds, you need amicrophone. Your microphone situation

depends on the kind of Mac you have:

• Laptop, iMac, eMac. You have a built-in microphone, usually a tiny hole near the

screen. This microphone couldn't be more convenient; it's always with you, and

always turned on.

• Other desktop Macs. You can plug in an external USB microphone (the Macintosh

Products Guide at www.guide.apple.com offers a list) or use an adapter (such as

the iMic,www.griffintechnology.com) that accommodates a standard microphone.

Tip: No matter which model you have, an Apple iSight videoconferencing camera works

well as a microphone.

The Sound pane of System Preferences lets you choose which sound source you want the

Mac to listen to. Click the Input tab, and then click the sound source you want: external

USB microphone, external analog microphone (that is, something plugged into the

microphone or Line In jacks of Macs that have them), built-in microphone, iSight, or

whatever.

15.2.1. Making the Recording

Once you've got your microphone situation taken care of, you need to get your hands on

some sound-recording software. You can use shareware programs like Amadeus II, or try

iMovie, GarageBand (both came with your Mac), or QuickTime Player Pro (read on).

15.2.1.1. The GarageBand method

Although you might never suspect it, every Mac comes with a basic recording program.

It's GarageBand, which lurks in your Applications folder.

Figure 15-2. GarageBand opens with a Piano track in place. You can delete it,

though (Track- Delete Track). What you want is a new digital-audio track,

which you get when you choose Track New Basic Track. You're ready to record

sound!
