Diagnostics > Delete Silence Should be recognized when recording a Macro
Currently, you cannot record a macro and include the Diagnostics>Delete Silence action in it. Attempting to do so causes an error message to occur saying something akin to no recognizable actions were entered for the macro.
In fact, it was confirmed by Adobe staff in 2014 that the macro doesn't recognize the Diagnostics panel. This works well with batch processing in Cool Edit Pro 2, and it's frustrating having to revert to legacy versions in order to get this to function. Please add it to Audition.
