another Plus-1 for spectral editing. The Spectral display and editing
feature in Audition makes cleaning up narration tracks easy compared with
wave-form editing. It is at least as big a jump in capability as moving
from analogue tape and razor blade to digital wave form editing. Various
mouth noises as well as extraneous noises like clothing rustles, stop
watch clicks, and script handling noise are easily removed... all not
really achievable or practical in waveform editing.

On the contrary I still find it better/easier to reduce plosives in waveform
edit, or fixed notch filter/s for any mains hum. Watch clicks or any other
short sharp spikes are probably easier done in waveform edit too IMO.
Spectral editing certainly works better for some things however.
