I have spent the last several days trying to understand the Round Robin process for Premiere and Audition, comparing CS5 and CS6.
With CS5, you have to send each clip separately to Soundbooth, after which you can use the Match panel, save the files, close SB, and the Premiere audio files update.
With CS6, you can select all the clips and send them to Audition, BUT if you drag them to the Match panel, perform something, then a "Doc_Match_" prefix is added to each one, preventing the updating. You can send a sequence to Audition, which gets complicated and which I haven't figured out completely yet.
Surely there must be a simpler way for CS6 to accomplish editing the audio of multiple clips. But I don't find any tutorials or books that describe one.
