Remove noise from phone recordings, fast
Phone recording plagued by hum, wind or background hiss? Learn how to remove noise and isolate speech for a clearer recording.
Why phone recordings get noisy
Phones record everywhere: cafés, streets, rooms with a fan running. Their small mics pick up both your voice and the hum, wind and background hiss. The result is a recording that's hard to use for a video, podcast or documentation.
Noise removal is a kind of separation: instead of splitting vocals from music, you separate the sound you want to keep (speech) from the unwanted noise.
How to clean up a recording
- Step 1: Upload the recording (mp3, wav, m4a, or the audio inside an mp4 video).
- Step 2: Choose the noise-removal / speech-isolation mode.
- Step 3: Process and preview — the background noise drops noticeably and the voice comes forward.
Note: noise removal is a separation kind TáchNhạc is still finishing. For now, the music separation tool can already isolate a voice from the background in many cases.
Tips to record cleaner in the first place
No tool can rescue a truly bad recording, so prevent problems up front:
- Record somewhere sheltered from wind, with little echo.
- Keep the mic close to your mouth and avoid touching the body.
- Turn off fans and air-conditioning while recording if you can.
- Record a few test seconds and listen back before the real take.
Combine good recording with noise removal afterwards and you'll get a clean recording good enough for most needs.
