Automatically Remove Breath Sounds for Free in Final Cut Pro

Breath sounds between sentences are one of the most noticeable marks of unpolished audio. On a close-range microphone, every inhale before a new thought is picked up clearly, and in a 10-minute video, manually cutting or fading 40 or 50 breath sounds is a significant time investment. Here's a way to handle it automatically and for free.

Why breath sounds matter

Breath sounds are a form of audio clutter: they interrupt the flow of speech without adding any information. Listeners rarely notice when they're removed (because the edit is seamless) but they do notice when breath sounds are prominent and distracting, particularly on sensitive microphones or in quiet studio-style recordings.

The issue is most pronounced on lapel mics, condenser microphones close to the speaker, and cardioid mics in quiet rooms. Dynamic microphones (like the Shure SM7B) are more forgiving because they're less sensitive to the subtle pressure changes of breathing.

The free tool: Adobe Podcast Enhance

Adobe Podcast Enhance (available at podcast.adobe.com, free with an Adobe account) uses AI to clean dialogue recordings. It removes background noise, room reverb, and, most relevantly here, it significantly reduces breath sounds by identifying and attenuating them automatically during processing.

Export your dialogue audio from FCP (select the clip, go to File → Share → Export File, and export audio only as WAV or AIFF). Upload the exported file to Adobe Podcast Enhance. Processing takes 1 to 3 minutes depending on file length. Download the enhanced version and import it back into FCP to replace your original audio track.

The manual approach in FCP

If you prefer to stay entirely within FCP, the manual process is: expand the audio waveform in the timeline (double-click the audio clip) to see the waveform at full height. Breath sounds appear as smaller, irregular waveform spikes between the larger spikes of speech. Select each breath using the Range Select tool, then press Option+Delete to replace the selected range with silence (or just Delete to leave a gap). Fade the edges of the selection in and out over 5 to 10 frames to avoid abrupt cuts.

This takes longer but gives you complete control: you can remove only the loudest, most distracting breaths and leave subtle ones intact, which sounds more natural than removing all of them entirely.

The FCP noise gate approach

FCP's built-in Noise Gate effect (Audio Effects → Levels → Noise Gate) can also help. Set the gate threshold so that quiet sounds (breaths) fall below the gate and are attenuated, while louder speech passes through unaffected. The challenge is calibrating the threshold: too aggressive and you'll clip the start and end of words; too loose and breath sounds pass through unchanged. It requires careful adjustment and works better on some recordings than others.
