Remove Background Noise from Audio — Free Online Tool
AI removes hiss, hum, HVAC noise, keyboard clicks, and room echo from any audio recording in seconds

The result is clean, professional-quality audio with the background noise removed.

Audio formats Voice Isolate supports
Voice Isolate processes all common audio formats: MP3 (the universal format for compressed audio), WAV (uncompressed, studio quality), M4A (Apple's AAC format used by Voice Memos and GarageBand), FLAC (lossless compression popular with audiophiles), OGG (open-source format used by Discord and some recorders), and AAC (raw AAC bitstream).
There's no need to convert between formats before uploading. The AI works on the decoded audio data regardless of the container or codec. Upload whatever format you have — the output will be a high-quality M4A (audio) or MP4 (video) file.
What types of audio noise can be removed
Background noise falls into two categories: stationary and non-stationary. Stationary noise is constant — HVAC hum, fan whir, electrical buzz, tape hiss. Non-stationary noise changes — keyboard clicks, a dog barking, a car passing, a door closing. Traditional noise reduction handles stationary noise well but struggles with non-stationary sounds. AI handles both.
- ●Stationary noise: HVAC systems, computer fans, electrical hum (50/60Hz), tape hiss, room tone, steady rain
- ●Non-stationary noise: keyboard and mouse clicks, traffic, construction, barking dogs, notification sounds, coughing, paper rustling
- ●Room acoustics: echo, reverb, flutter echo between parallel walls, comb filtering from reflective surfaces
- ●Equipment noise: mic self-noise, preamp hiss, ground loop hum, USB interference, wireless mic dropouts
When to use audio noise removal
- ●Podcast recordings where the guest was in a noisy environment
- ●Voice memos and phone recordings used for transcription
- ●Interview audio captured in public spaces, coffee shops, or outdoors
- ●Lecture recordings from classrooms with poor acoustics
- ●Voiceover recordings made in untreated home studios
- ●Audio from security cameras, dashcams, or body cameras
- ●Music rehearsal recordings where you want to isolate discussion between takes
