Music and Audio

The Power Mac G5 supports more tracks and more plug-ins than any previous Power

Mac, giving audio professionals a wealth of creative options—all in a native environ-

ment. In addition, Mac OS X Core Audio offers a scalable platform supporting 32-bit

high-resolution audio, a plug-in called Audio Units for DSP and Virtual Instruments,

and plug-and-play connectivity for modern and legacy audio gear. The built-in optical

S/PDIF connects to other audio equipment for pristine sound quality without trouble-

some ground loops.

Logic

To quantify the performance advantages of the Power Mac G5 for audio production,

Apple tested Emagic’s Logic Platinum 6.3.1. Apple created a processor-intensive work-

load containing multiple unique audio tracks, assigned five default reverb plug-ins to

each of the audio tracks, and tested each platform to see which application could play

more plug-ins.

The dual 2GHz and dual 1.8GHz Power Mac G5 systems can play 155 and 137 plug-ins,

respectively, compared with a maximum of 64 plug-ins on the Dell Dimension XPS and

84 plug-ins on the Dell Precision 650. Impressively, the 1.6GHz Power Mac G5 played

23% more plug-ins than the 3.2GHz Pentium 4–based system.

Power Mac G5 systems were tested using Logic Platinum 6.3.1. The Dell Dimension XPS, Alienware Aurora, and Dell

Precision 650 were tested using Steinberg Cubase SX 2.0.1.
