Editorial interest 78/100 Selection signal · not a rating of the site

A free Mac microphone app that removes background noise and offers four voice tones, from “As is” to “Broadcast.”

Landing page captured for the 2026-11-04 issue.

For: Mac users who want consistent call audio across apps
Worth noticing: The app offers a six-second before-and-after self-playback and lists separate processing settings, including a 50/60 Hz hum filter.

Field notes

The described workflow adds a selectable system microphone, so the same settings can be used wherever a call app accepts an input-device choice. The page lists distinct processing options, including automatic 50/60 Hz hum filtering, leveling to −20 dBFS, and voice presets with specific EQ and compression values. It identifies the download as free and lists macOS 14+ and Apple Silicon requirements.
