Read moreCan ChatGPT remove background noise from a video?

Read moreWhat is the difference between removing noise and enhancing voice?
Noise removal reduces unwanted sound already in the recording. Enhancing voice also reshapes the voice. Rushilo's 1.2.0 notes describe Enhance voice as rebuilding the missing top end of phone, headset and call recordings on your computer, while 1.1.0 added a one-click Clean mic noise toggle.

It can, especially when cuts clip nearby sounds or remove the pause between ideas. Podcasters in r/podcasting report that stripping every um sounds stilted. Remove the distracting ones, avoid cutting fillers that run into the next word and keep breaths and short pauses.

Read moreWhat loudness should a podcast episode have?
Apple Podcasts suggests overall loudness near -16 LKFS, within 1 dB. Follow your host's own spec, since no single figure fits everywhere, and check the encoded file before upload. Rushilo measures loudness in LUFS and normalises to a target.

Read moreHow many frames are in a beat?
