What is the best free way to denoise audio?

Upload the file here and use Balanced strength. A free account includes 30 minutes of denoising with no watermark, and you can compare before and after before downloading.

Is AI denoising better than Audacity noise reduction?

For changing noise like traffic, chatter or wind, usually yes: Audacity subtracts a fixed noise profile, while the AI adapts frame by frame. For steady hiss both can work well.

Does denoising reduce audio quality?

At very high strength any denoiser can make a voice sound processed. That is why you can choose Light, Balanced or Max and compare with the original.

Which model does the denoiser use?

DeepFilterNet3, an open-source speech enhancement model, running on our own servers. Your files are deleted after 24 hours.

How AI noise reduction differs from a noise gate

Classic denoisers take a noise profile from a silent part and subtract it. That works for steady hiss, but it struggles with changing noise like traffic or chatter, and pushed too far it leaves a watery, 'underwater' sound.

This denoiser uses DeepFilterNet, a neural network trained on thousands of hours of speech and noise. It decides frame by frame what is voice and what isn't, so it handles changing noise without a noise profile.

Choose the strength
Light keeps some room sound, Balanced suits most files, Max removes the most.

As MP3, WAV or the same format you uploaded.

Denoising tips

Denoise before you compress or boost the audio; boosting first makes the noise louder.
If the voice sounds thin, step down from Max to Balanced or Light.
Use WAV output if you plan to edit the file further.

What it removes, and what it keeps

Every noise lives somewhere on the audio spectrum. The AI learns what a voice sounds like and turns down everything else, even where they overlap.

20 Hz100 Hz1 kHz10 kHz20 kHz

Your voice, kept

Speech sits between about 85 Hz and 8 kHz. That's what we protect.

Hum and buzz

50/60 Hz electrical hum, ground loops and buzzing lights.

Wind noise

Rumble and buffeting from outdoor vlogs and phone videos.

Traffic and street noise

Cars, buses, horns and crowds behind on-location recordings.

Room and café chatter

Clinking cups, keyboard clicks and background murmur.

Hiss and static

Mic hiss, fan and AC noise, and preamp static.

Background music is treated as noise too, because the AI only keeps speech. If you need the music, add it back after cleaning the voice.
