Depends what you mean by "optimal" in my case file size is the key
variable, download time.
full resolution WAV to mp3 --> 56k
Full resolution WAV to AU --> 114k
56k mp3 (same audio) to AU --> 56k (assumes want to import rev audio
clip)
difference in quality between the 114 K au file converted from full
resolution file and the same audio.au converted from the mp3 --
practically indiscernible to my ear. but < 1/2 the size. So, this
breaks the rule but does make some kind of sense... 20 VO captions at
56k - 1MB+ 20VO captions at 116K @ = 2MB download....

exactly... benefits:
1) auto scripted naming of the caption VO files to match filenames of
slides
2) on board teleprompter either by simply viewing the slides and then ad
lib the audio (for Q and D productions), or set up caption fields,
script/practice the captions in advance for more careful delivery...
3) apples scripted 'drivers' for external processing
etc. never switch to another program... (set up Switch in the background
to handle files in a watch folder... )

I recorded some simple audio using Apple's Sound Track Pro using our
super hi-end Newman BCM104 broadcaster's microphone (incredible
quality!) vs Quick and Dirty recording in RunRev saving to WAV using the
Samson USB mic. processed both files (to MP3 using Switch) all the way
down to 56K mp3 and compare: OK, yes, the Newman gives a bit more
"rounded" quality, but the RunRev --> WAV -- mp3 was certainly OK for
our needs.
