Denoiser: AI Noise Remover

Strip background noise, transcribe offline, and split songs into vocals + instrumental — 100% on your iPhone. Nothing is ever uploaded.

Hiss. Hum. Traffic. Wind. Your recording deserves better.

Denoiser is a private, on-device audio studio for iPhone. It removes background noise, transcribes speech offline, and splits songs into vocals and instrumental — with nothing ever uploaded. It works the same in airplane mode.

CLEAN — REMOVE BACKGROUND NOISE • Record or import audio and video (the video's audio track is used) • One tap reduces fan hum, street noise, hiss and wind with on-device processing • A/B compare before & after instantly; pick light, medium or max strength • Export clean audio, or remux the video with its original picture untouched

TRANSCRIBE — OFFLINE SPEECH TO TEXT • Fully on-device Whisper transcription — no cloud, no account • Timestamped paragraphs: tap a paragraph to jump playback • Edit inline, then export TXT, SRT, VTT or Markdown subtitles • Voice-activity detection skips silence and avoids hallucinated text

STUDIO — SPLIT VOCALS & MUSIC • Separate an imported track into vocal and instrumental stems, entirely on device • Preview the two stems separately; export a karaoke track or both stems

PRIVATE BY DESIGN No servers, no uploads, no sign-in, no tracking, no ads. Your recordings, transcripts and files stay on your iPhone unless you choose to share them. Audio-processing tools require iOS 17 or later; iOS 14–16 provide compatibility previews only.

FREE TO TRY Preview the first 30 seconds of each supported file for free. Pro unlocks processing beyond 30 seconds: up to 10 minutes for Clean and Transcribe, and up to 5 minutes for Studio, plus all exports.

— Denoiser Pro — • Lifetime — $29.99 one-time purchase • Yearly — $19.99 with a 3-day free trial • Weekly — $2.99 Pro unlocks processing beyond the 30-second preview within the supported 10-minute Clean/Transcribe and 5-minute Studio limits, plus all exports and skins.

SUBSCRIPTION Denoiser Pro offers auto-renewable subscriptions (weekly and yearly). Payment is charged to your Apple Account at confirmation of purchase.
