Audio Denoiser

Removes background noise from audio files. Targets steady noises like AC hum, fan whir, tape hiss and static.

What it does

Use this to reduce air-conditioner noise on meeting recordings, clean traffic rumble out of interviews, or get rid of the static on tape transfers.

How to use

  1. Drag audio files into the list.
  2. Adjust the Reduction Strength slider (default 75%).
  3. Leave Optimized for Stationary Noise and Auto-Sense on.
  4. Click Run.

You get one cleaned-up copy per file.

Settings

  • Reduction Strength (0-100%): Low means gentle cleanup (stays close to the original), high is aggressive. 75% is balanced, 90%+ is heavy-handed.
  • Optimized for Stationary Noise: When on, targets steady sounds like AC and fan. Leave on for speech.
  • Auto-Sense Noise Floor: Picks a noise sample from a quiet section. If off, applies a generic cleanup to the whole file.

Examples

Meeting recording with AC noise: Add the file, Strength 75%, defaults, run. Speech becomes clearer.

Old tape with static: Add the tape transfer, Strength 85%, run. Static drops sharply.

Interview with traffic rumble: Add the interview, Strength 70%, run. Speech is preserved, noise drops.

Studio recording with slight hum: Add the file, Strength 50%, run. Gentle cleanup, no quality loss.

Watch out

  • This works well on steady, ongoing noise. Sudden noises (a door slam, a cough) are not really what it targets.
  • It does not remove echo. You need a different tool for that.
  • Very high strength makes the voice unnatural and robotic.
  • On music it strips detail, do not use it on music.
  • In Auto-Sense mode, files without any quiet section produce inconsistent results.
