The Audio area
The Audio area grants an overview of audio statistics and can be used both to measure CPU Usage from the audio system and total memory consumed by audio sources (both for those that are playing or paused) and audio clips.
Breakdown View provides lots of useful insights into how the audio system is operating and how various audio channels and groups are being used.
The Audio area may come in handy as we explore art assets in Chapter 4, Optimizing Your Art Assets.
Audio is often overlooked when it comes to performance optimization, but audio can become a surprisingly large source of bottlenecks if it is not managed properly due to the potential amount of hard disk access and CPU processing required. Don't neglect it!
