What it is

DeNoizzer is a noise reduction and restoration plugin from W.A. Production that isolates and eliminates unwanted noise frequencies from recordings. Instead of relying on a blunt noise gate, it learns a custom noise profile from an isolated sample of the offending sound and removes it with surgical precision, leaving the rest of the signal intact. A real-time spectrum display shows both the incoming and processed signal so you can see exactly what's being removed as you dial in settings.

Who it's for

Producers and audio engineers cleaning up imperfect recordings, whether that's room ambience, electronic hum, traffic rumble, or other intrusive background noise in vocals, dialogue, or instrument tracks.

Key features

• Learns targeted noise profiles directly from isolated audio samples rather than using a generic gate
• High and low-pass filters narrow in on problem frequencies without touching the rest of the spectrum
• Listen mode lets you monitor the isolated noise on its own to confirm what's being removed
• AB comparison, undo/redo, and adjustable resolution and speed response controls make it easy to fine-tune results without guesswork
