How to Remove Background Noise from a Voice Recording on iPhone
Hiss, fridge hum, traffic, that faint AC drone — background noise is the #1 thing that makes a phone recording sound amateur. Here's how to strip it out in one tap and keep your voice sounding natural.
Know your enemy: the 3 types of noise
- Broadband hiss — the constant "shhh" floor from mics and quiet rooms. Isolate Vocals handles this best.
- Hum and rumble — AC units, fridges, traffic through walls. A mix of vocal isolation and low-cut EQ.
- Room echo/reverb — reflections off hard walls. Hardest to remove after the fact; best prevented by recording in a soft-furnished room.
Cleaning a noisy recording, step by step
- Open the recording in Voice Tune. Record directly in the free app or import a take you already have.
- Turn on Isolate Vocals. Tap Adjust and switch it on. It lifts your voice out of the recording and leaves the steady background behind — hiss, hum, room tone — which is exactly what de-noising is, done by separation rather than by gating.
- EQ out the rumble. In the same sheet, open the Equalizer and pull down the lows beneath your voice. Almost everything below a male voice's low notes is noise, not signal.
- Compress gently. The Compressor raises quiet phrases and tames loud ones, which lets you keep the overall level lower — and lower level means the remaining noise floor is even less audible.
- A/B and export. Compare with the original by toggling the effect off and on. If the voice sounds "underwater" or robotic, the separation is working too hard on a very noisy source — back it off and let a whisper of room tone remain.
Prevention beats removal
- Record 15–20 cm from the mic — closer voice means better voice-to-noise ratio.
- Choose soft rooms: curtains, carpet, a closet full of clothes is a legendary vocal booth.
- Silence what you can: fans off, windows closed, phone on Do Not Disturb.

Common questions
Can I remove background music from behind a voice?
Yes — it's the same tool doing the same job on a harder source. See how to isolate vocals from a song.
Will noise removal change how my voice sounds?
On a reasonably clean take it's transparent. On a very noisy source the separation can leave artifacts — if you hear them, turn the effect off and lean on EQ instead, or re-record in a quieter spot.
Does this work for podcasts and voiceovers, not just singing?
Yes. Isolate Vocals + EQ + Compressor is exactly the chain podcasters use — and the Podcast template sets up broadcast-clean speech in one tap, with no tuning applied.
