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.
