Looking for suggestions for work flow when editing multitracks for a podcast

De-umming and de-erring is one of the few tasks that I think it's worth doing in Waveform view. As long as you retain a sensible flow, you won't want to redo it, and it means that if you put marker ranges around the bits you want to keep when you've tidied them up, it's easy to drop them straight into your multitrack session. One thing that unfortunately Audition won't do at present is to let you set sensible speeds for that J,K and L keys - it jumps straight from x1 to x2, and x2 leaves speech sounding unrecognisable. If it had x1.25 and x1.5 as well, especially without a pitch shift, it would make locating gaps, ums and errs a lot quicker, and speed up one's workflow significantly. (I think that the chances of me getting that added are pretty slender, unfortunately, but I'll give it another go...)

Other than that, the only other thing I can tell you is that after a while, it gets quicker to locate all these things visually, as well as with your ears - pay careful attention to the waveform itself; it can tell you a lot!
