De-esser for recording in Keynote?

[neutrino23]

I record presentations in Keynote and export them as videos as well as presentations. I find that I have a moderate ess in my voice. Is it possible to run some sort of pre-processor plugin with macOS to de-ess and compress my voice between the microphone and the recording in Keynote?

Alternatively, I could export the video, extract that audio and copy it into GarageBand and process it there before playing it back into Keynote. I don't need pro-level results, but if I can easily sound better that would be great. Can someone point me in the direction of learning to do this?

I've experimented with microphone positioning and a pop-filter and that helps. I'd like to go a step further.

I'm using an Audio Technica AT2020 USB mic.

Thanks.

Pre-processing will probably not be an option in keynote.
For post-processing you might try this one: http://www.musicradar.com/news/tech/free-vst-au-de-esser-toneboosters-sibalance-cm-632437#
You'll need a AU/VST capable program though.

Thanks. For our sales reps I like to record a presentation directly in Keynote. If they are not familiar with the topic they can use my recorded presentation. Otherwise they can manually drive the presentation and do their own narration. I can do post processing but it is a lot more work.

Locating the microphone down around chest level so that I'm not speaking directly at the mic and adding a good pop filter has helped a lot.

Using Audacity, you could do some fairly quick and easy post-processing (and it can use VST plug-ins, too). Most people, myself included, are somewhat sensitive to/critical of their own voice. Is there someone you respect who can give you an eval of your recorded output. It may be less of an issue than you think.
