I've been experiencing a LOT of RAM usage. Audition CS6, version 5.0.2, Build 5; Mac Mini, OS 10.8.3, 2.5 GHz Intel Core i5, 16 GB RAM.
I just finished a mono voice recording (16 bit/44.1k) of just under an hour. The RAM usage when recording began was about 3.3 GB. When the recording was finished, RAM usage had jumped to over 12.5 GB. Just making a recording, with no other applications running (which I do purposely to avoid disruptions).
I've also had similar memory usage while editing; so much so, that I would have to quit and even reboot the computer to regain all available RAM before continuing. Audition has never crashed because of this – I've always caught it in time (I have RAM readouts in my menu bar) – but Audition gets extremely sluggish. Even when quitting. On quitting, the GUI will immediately disappear, but Audition menus remain in place for about 15 seconds before they finally go. But the computer is still sluggish even when I call for a restart.
This sure is time-consuming.
Any help would be greatly appreciated. Thanks.
