Denoiser: AI Noise Remover

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.
