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 -
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.
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.
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.
