What Does the Denoiser Do?

Recordings made outside a treated studio often pick up background noise — a fan or AC hum, street noise, wind on a phone mic, or a faint electrical hiss from cheaper recording gear.

This tool runs a general-purpose AI speech-enhancement model over your upload and suppresses that background noise, leaving the voice or vocal itself intact — without changing pitch, tempo, or the actual performance.

When to Use It

🎙️ Noisy Recordings

A voice memo, interview, or vocal take recorded outside a treated room usually has some background noise baked in — this cleans it up.

Frequently Asked Questions

Is the vocal denoiser really free?
Yes, completely free. No trial period, no credit card, no catch.
Will this remove all background noise?
It significantly reduces steady background noise (hum, hiss, fan/AC noise, wind) and complex ambient noise alike. Very loud or unusual noise sources may not be removed 100% — this is a real limitation of current AI denoising models, not a bug. Results are typically noticeably cleaner than the original.
What's the difference between this and the Dereverb tool?
This removes background noise (hum, hiss, wind, ambient sound). Dereverb removes echo/reverb — the reflections of the sound bouncing around a room. A recording can suffer from either, both, or neither — use whichever one matches your problem, or both in sequence.
What audio formats can I upload?
You can upload MP3, WAV, FLAC, M4A, AAC, OGG, AIFF, WMA, Opus, AMR, APE, WavPack (WV), and most other common audio formats. You can also upload video files (MP4, MOV, MKV, AVI, WebM, FLV, WMV, MPG, 3GP, and more) — we'll automatically extract the audio track. Maximum file size is 100 MB for audio, 1 GB for video. Audio longer than about 10 minutes may not finish processing in time — for best results, keep uploads under 10 minutes.
What format is the output file?
The denoised track is delivered as a high-quality MP3 file.
