Finally, there's the new Movie Score project option and several useful podcasting tools. GarageBand 3 includes a drag-and-drop artwork feature that allows you to easily add visual enhancements to your podcasts. (Newer iPods are capable of playing these tracks with the timed-in art.) Apple has also added more than 100 royalty-free jingles and a generous number of radio-style sound effects, called stingers. But the icing on the cake are the speech-enhancer effect, which reduces background noise and brings vocals forward, and the ducking effect that automatically lowers background music when a speech track comes in. The latter is especially time-saving.
While audio pros won't be satisfied with GarageBand 3 alone, the program is a good choice for novice music production. In addition to the features mentioned above, there's a basic mixer for each track that lets you adjust the left and right balance as well as fade the volume in and out. You can also import audio (AIFF, WAV, MP3, Apple Lossless, and unprotected AAC) and MIDI files by dragging and dropping them into the interface, and GarageBand 3 has the ability to display recordings in full musical notation. The app also lets you edit individual tracks, but we were unsatisfied with the level of editing; you can't get down to the audio sample level. Pick up a separate audio-editing tool such as Bias Peak if you need this functionality. Once you've completed your GarageBand music project, you can export it to iTunes as an AIFF file. Within iTunes, you can then convert the file to an MP3 or AAC track.
As one would expect, GarageBand 3's performance varies based on the system. Interestingly, when we tested the latest version of the program on a G4 PowerBook with a 1.67GHz PowerPC processor and 512MB of RAM, we got the same performance as we did when testing version 2 on a G4 iBook with a 1GHz processor and 256MB of RAM, even though the PowerBook had a more optimal configuration. (Apple recommends 512MB of RAM and requires that you have Mac OS X 10.3.9 or later or Mac OS X 10.4.3 or later.) Essentially, performance was a bit sketchy at first, with the app skipping and halting with as few as four tracks playing. Luckily, the help menu includes tips for optimizing GarageBand 3--for example, not running apps in the background and locking individual tracks--and once we utilized these tricks, we experienced few problems.
All editing and effects processing happens in real time, with little if any delay. However, we had some latency issues when previewing loops while consecutively playing back tracks that were already laid down. Results varied, but there was always a noticeable delay between clicking the loop and the playback of that preview; occasionally, the main tracks would stop playing completely. As such, we found it more useful to drag loops into the interface and listen to them there; sometimes, we noted a lag between dropping the loops and their actually showing up. This lag became more and more noticeable as we continued to add Jam Packs. These performance issues combined with the huge amount of space required by the program leads us to the conclusion that GarageBand is best suited to a powerful desktop configuration.
In addition to the tips found in GarageBand Help, Apple has a GarageBand support Web page. Here, you'll find community forums for each program in iLife, as well as software updates and an extensive list of linked support topics. Apple also offers complimentary support via e-mail, chat, or phone for the first 90 days that you own the software.
