Basically the process is the same but I used a well known tool call BeSweet which also suggests BeSweet GUI. It takes the AC3 stream and in one process converts it into the 6 mono channel WAV’s which I can then process using Adobe Audition 1.5. Sadly I’ve not been able to get the DTS decoding to work using BeSweet though I should be able to. It’s much quicker than using Graph Edit since that produces a WAV file that does actually have 6 channels but you have to use the WAV2WAV6 to split the channels out into mono WAV’s. And like I said previously it mixes up the right and center channel which can be confusing at times.

Since I posted a DTS sample, here’s a nice AC3 sample.
