Is there a way to "burn" audio to an ISO? (as an audio CD)

Solution 1:

It's not free (30-day trial, though), but FWIW this program appears to be one of the few that might be able top do what you're looking for: http://www.virtualcd-online.com/vcd/apps/overview/features.cfm?lg=0

(the "Burning" tab on that page states "Burn virtual CDs and ISO images")

Not sure if it would work for your particular circumstances or not.

Solution 2:

Ultra ISO will do that for you, one of its feature is to "Create/Edit Audio CD Image" to bin/cue format, I have used it to create many Audio CD Images, which I then mount and listen to.(Thats called listening with style!)

Solution 3:

Here's a different route to your problem. I suppose it should solve it. How about playing it in whatever proprietary software it uses, and recording what comes out the speakers(windows lets you do that). Open volume control, go to options..properties..recording... choose stereo mix and mono mix ok, then tick one of those.

now open a program like start..run..sndrec32 or something more flashy, and press record and play the cd.
