http://www.google.com/search?hl=en [...] c3+to+wav. I
believe AC3 is surround format so you'll probably need something to convert
them back into the AC3 file:

Thanks. What would you use to convert WAV to AC-3 2.0? I tried Sony's Vegas,
but haven't been able to check the quality of conversion.

The reason I need it is I'm trying to choose whether I should go with Dolby
Digital soundtrack AC-3 2.0 448kbs or with mp2 soundtrack encoded with tooLame
at 384kbs for the DVD I'm making.

Thanks for bringing the frequency issue up Leonid. I ran a converted file
through Sound Forge's spectrum analysis tool and was quite surprised
(disappointed) to see the result :-(

I've tried it before but, even with the GUI, AC3Decode is so much easier.
Oh well, time to look again at quality versus convenience, I guess :-)
