I have a Griffin iMic USB audio interface thing, into which I plug a

can select it in the Sound sys prefs panel as my input device, and
away I go! Then Rev 'hears' it just fine.

OK, yes, it works... but one must stick with the default codec
"none" ... any attempt to set it to ulaw with the USB mic doesn't
work... and touching the input setting can also be a problem (i.e.
"dflt" is what we want.... nothing else)
But anyway, it doesn't seem to matter too muich. For voice I'm
getting small file sizes at 16 bit, 22.01kHz. (8 bit introduces to
much hiss and pops.) Setting the record format to "wave" and the file
extension to ".wav" means it boots on both platforms which is
great... WMP on Windows and QT on the Mac.
[ if you want quality -- giant files...
set the recordsamplesize to 128.21
set the recordrate to 44.1

uLaw 2:1 codec and recordformat "ulaw" and file extension set to
".au" gives me only only a slightly smaller file for the same length
of time at 22.01 16 bit, but those settings only work with the
internal mic...and that's bad quality. If I try alaw with the USB
mic I get some horrible screeching noise that won't stop until I quit
revolution!
My problem was trying to use the codecs, instead of just going with
the default compression "none" -- OK... I'm good to go: for voice
annotation of photos, email attachments at 22.01, 16 bit, we get
really small files and perfectly acceptable quality.

Katir,
I use my USB adapter for recording with rev all the time. (OSX).
Just go to the system preferences -> sound -> input and select your
USB device (needs to be plugged in, of course.) I haven't tried
selecting it via rev, though.
You _may_ have to do this before starting rev. I'm pretty sure I
had to restart Audacity before it would recognize it...or was that
Win98?....
Anyhow, it's very doable.
