NoisyNo: Voice Noise Remover

Remove background noise, hum, hiss, fan noise, and room sound from voice memos, video clips, lectures, interviews, and podcasts. Fully offline.

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 • 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 (24-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.
