I'm surfing the web and reading tutorials while waiting for “Render and Replace” to finish. I selected two audio clips that are really a contiguous recording broken up at the 2GB file size limit by the recorder.
It's taking a long, long, time.
(later) it is taking a long time for Audition to load the PCM, too.
Is there, in general, a good way to move relevant files temporarily to local storage, and then move them back? I'm not just editing the project on the local drive and archiving to the NAS when I'm done; I'm keeping the media files on the NAS normally for robustness. But since media is read-only, can't it “shadow” them locally?
This rendering step seems to be very inefficient somehow. It's not anywhere near the LAN bandwidth, which is nearly as fast as local storage for sustained transfers, but takes longer to open/close/seek, and repeated reading is bad because the OS doesn't cache it like it does with local files. OTOH, it showed a CPU usage that is typical of a CPU bound single thread: maxing out one core out of 6, or 17%.
With other workflows, in the past I've made two directories with the same name/relative-path but on different drives; using one for input and the other for output speeded things up but the project directory was split.
