Creating 5.1 AC3

I have created 6 mono racks in Adobe Audition that I need to convert into a 5.1 AC3 file. I have tried BeSweet/BeLight/BeSweetGUI and cannot seem to make it work (I read one post that said the BeSweet MUX facility is not working on the current betas). BeSweet can't seem to read either the 6-channel wavs nor the mono wavs that Audition creates. This is a one-time project, so I really don't want to buy some expensive software (Acid, etc). What are my options? Thanks.

Try ffmpeg. Commandline would be like

ffmpeg -i input.wav -acodec ac3 -ab 448 out.ac3

Latexx,
Thanks for the suggestion. I get an error message saying "unsupported codec for input stream". Maybe I don't have the correct libavcodec? If so, where can I get the correct libavcodec?

So it appears that ffmpeg doesn't like multichannel wav as input. You could try mencoder next.
