Remove Background Noise from Audio, Every Setting (Free)

Every setting of the free Noise Reduction tool on a voice note recorded with a fan running (noise floor -41.7 dB, no mains hum): the Podcast default (AI Voice, floor down 10.5 dB with 0.55 dB of the voice lost — measured on the finished file), Meeting (the pauses become digital silence), Music and Vinyl, then Spectral mode on the same fan — down 22.5 dB — the three modes and when each wins, and the gate. Three jobs. Nothing is uploaded.

Noise Reduction, every setting, on a voice note recorded with a desk fan running. The file is measured on the way in (noise floor -41.7 dB; it also looks for mains hum and offers to notch it). The Podcast preset runs a rumble filter and AI Voice at 75%, and the finished file is measured again: the floor is down 10.5 dB with only 0.55 dB of the voice lost. Meeting goes harder, with a gate, and the pauses become digital silence; Music uses the gentler Spectral mode, because AI Voice treats anything that is not speech as noise; Vinyl adds click removal. On steady noise like a fan, Spectral mode brings the floor down 22.5 dB. Noise profile learns from a stretch of pure noise you drag across. Free cleans one file up to 50 MB and 15 minutes; Pro takes 25 files and higher-quality output. Nothing is uploaded.
