I am using a 2010 Macbook Pro (with OSX Lion) and Apogee Duet 2 audio interface (USB) and Focal powered monitors (or headphones).
Can someone explain why, when I listen to an Amadeus file my computer heats up and the fans often start blowing loudly, but when I place the same file in iTunes and play it back, there are no such problems?
The typical file is a standard CD rip, with just a couple of tracks or sections edited out.
When the Amadeus file is replayed (in Amadeus Pro), the computer's Activity Monitor shows an Amadeus Pro %CPU of between 16 and 24.
When playing the same file (saved as an AIFF) in iTunes, the %CPU is only around 4 or 5.
Is there something I need to be aware of that will enable me to avoid the heat and fan noise issue? Do the above CPU readings indicate any abnormality? Thanks.

Remember AP is scrolling the window and the data while Itunes doesn't.
That means lots of rewrites of the screen. Those don't come for free.
Possibly if you compressed the window to a narrow width, then the load
would be less.
