After your audio has been cleaned up, I move on to the enhancing stage. A lot can go into this process, but I won't bore you. These are the 3 biggest tools audio engineers use for spoken word.

This is where Eq (equalisation), compression and de-essing come into play - 

Eq -

This is where I bring out the best in your voice, and quieten down any undesirable tones. Usually, I will bring up a touch of low-mids (this is where the power is in your voice), and bring down any nasally higher frequencies. 

Compression -

This stage balances out the sound. Expression is always good in podcasts and audiobooks, but you don't want to give your listeners a fright if you raise your voice, and you don't want them reaching for the volume just to catch a more somber moment. In a nutshell, compression balances out the difference between the loudest and the quietest parts, resulting in a more consisted volume throughout without compromising the energy and expression in your voice.   

De-essing -

Those harsh 'sss' sounds and whistles you hear when listening to raw spoken word recordings. Not only can it be a distraction, it can also be painful to listen to especially when wearing headphones. These harsh sounds have no place in your audio, so I'll be getting rid of them.
