I have not used Audition much, I used to use Cool Edit.
A useful facility in Cool Edit once you got down to fairly fine detail was to push the individual dots (representing the bit value) up or down with a mouse. This was particularly useful when re-shaping the peak of a clipped waveform, say. In Audition, I can't do this, or not in the same way. The only way I have found to do this is to select an individual dot and amplify it up or down, then select the next one etc. This is very laborious. I am sure there must be a better way.
I used to manipulate at the 'dot' level before xfades were introduced - since then never found the need
I'm afraid there isn't a better way to manipulate individual samples, as SuiteSpot has observed. But since then, a much more reliable and technically more accurate way of de-clipping has been introduced, eliminating the need for being able to do this manually, completely: Effects>Diagnostics>DeClipper
