Remove wet mouth noises with this plugin from iZotope

“Wet” mouth noises are very common in podcasting, and luckily, thanks to an excellent filter from iZotope, you can easily remove them.

This is a gross topic and I’m already cringing as I write it, but it’s important to address. You may hear these wet or click-y noises caused by saliva as one of your panelists speaks, and you know that your listeners won’t want to hear them either.

Unfortunately some people always have these noises and there isn’t any way of naturally getting rid of them. That’s why I’m grateful for iZotope’s “Mouth De-click” plugin, which is available as part of their RX8 Standard and Advanced apps.

Using their presets and a couple of simple sliders, you can easily remove mouth noises from your panelists’ tracks. In my experience this filter has worked REALLY well, and I can no longer imagine my editing life without it. Whether or not a panelist has loud and frequent mouth noises, I run this filter on all of my tracks so that I can erase even the littlest wet bits.

I haven’t encountered any downsides after running this filter on my files. The audio remains in very high quality post-filtering and 99% of the clicks are removed.

If you’re finding that iZotope is having a hard time removing clicks from a particularly wet mouth, bring those ‘Sensitivity’ and “Click Widening” sliders further to the right. Just be sure to preview the filtering before applying it, because too much click widening can cause syllables to be dropped.

iZotope’s RX is some expensive software, but it’ll be well worth the investment over the long term. Mouth De-click is my favorite plugin from them, but there are other good ones like De-ess, De-Crackle, De-Reverb, and De-Clip. After purchasing RX, you’ll also be able to add these plugins to audio editors like Adobe Audition.
