Denoise is an Android and iOS app for cleaning up audio in voice memos, interviews and videos. Its on-device neural network reduces wind, traffic, hiss, hum and crowd noise, and runs offline, including in airplane mode. Recordings can be imported from Voice Memos, Photos, Files or an app share sheet; supported inputs include MP4, M4A, MP3 and WAV. Pro can export M4A, MP3 or WAV and replace a video's audio. Its VoiceFixer engine rebuilds detail in clipped, muffled or distant recordings, while version 4.0 separates vocals and instrumentals on-device. A five-band EQ offers Voice, Phone Call, Lecture and Music presets, with automatic loudness normalization at −16, −14, −19 or −23 LUFS. There is no file-length limit, including for recordings up to a three-hour lecture. Processing stays on the device, and Routes Software says recordings are not uploaded or stored; the app has no user accounts. Google Firebase collects anonymous usage analytics and diagnostics. Free users can denoise and preview, but saving and export require Pro. Pro costs 2.99 USD per month or 14.99 USD once for lifetime access.
