Offline audio noise cleaner

Free · In-App Purchases

Remove background noise offline, then normalize loudness for audiobooks, podcasts, or video with LUFS presets and custom targets in Pro. NoisyNo is a voice noise remover that strips background noise from recordings and video audio — fully offline, right on your device. Drop in a voice memo, video clip, lecture, interview, meeting, or podcast recording. NoisyNo isolates the speech and removes hum, hiss, fan noise, A/C buzz, wind, and ambient room tone. Compare the before and after, then export the cleaned audio file. Why NoisyNo • Offline background noise removal — audio never leaves your iPhone • Voice-first cleanup — tuned for speech, not music • Pro loudness normalization — match audiobook (−18 LUFS), podcast (−16 LUFS), video/streaming (−14 LUFS), or a custom target • Before vs. after preview — hear the difference before exporting • Tap-to-seek waveform — scrub through to confirm the right take • Output your way — M4A (AAC) for sharing, WAV (16-bit) for editing • Simple workflow — import, denoise, compare, share Made for • Voice memos and dictation • Lectures, classes, and online courses • Interviews and podcast clips • Meetings, calls, and Zoom recordings • Video clips, field recordings, and content drafts • Microphone takes from noisy rooms, cafes, or outdoors Private by design No uploads. No accounts. No cloud processing. Every file is denoised on-device using a local model, then stored only on your iPhone unless you choose to share it. NoisyNo is built for quick speech cleanup and noise reduction — when you want a clearer voice and less background noise, without launching a full audio editor.
