AI Audio Denoise — because half of video quality is sound

The four audio modules

Audio denoising

Strips steady background noise — hum, hiss, air conditioning, traffic bed — while keeping speech intact.

Voice enhancement (dereverberation)

Reduces room echo and boosts vocal clarity, rescuing interviews and lectures recorded in untreated spaces.

Vocal separation

Splits a mixed track into vocals and accompaniment — isolate dialog from background music, or extract an instrumental.

AI voice change

Transform a voice toward a chosen timbre or character voice. Preview first — identity shift is a creative choice, not a cleanup default.

Audio is the quality signal people actually notice

The practical wins are everyday ones: an interview recorded next to an air conditioner, a lecture captured in a reverberant hall, a family tape with the dialog buried under background music, or a voice that needs a different timbre. Those map to denoise, dereverb, separate, and voice change.

What AI Audio Denoise can and cannot fix

Steady, broadband noise and room reverb respond very well. Clipped audio — where the waveform was distorted at recording time — can be improved but not fully un-clipped; that information was destroyed at capture. And vocal separation quality depends on the mix: dense productions separate less cleanly than a voice over a music bed. As everywhere in KwaFlux, the preview-first workflow lets you hear the result on your own material before committing.

How to clean up audio with KwaFlux

1. 01

   Import video or audio

   The modules work on a video's soundtrack directly or on standalone audio files — no need to extract tracks first.

2. 02

   Pick the problem

   Denoise for background hum and hiss, voice enhancement for echoey rooms, vocal separation to pull dialog or vocals out of a mix. Preview to hear the difference.

3. 03

   Export locally

   Render on your machine and, for video, re-export with the cleaned track in place — picture and sound fixed in one pipeline.

System requirements

Operating system

Windows 10 (64-bit, 1809+) or Windows 11

macOS build coming — planned minimum macOS 13 or newer (Apple Silicon and Intel).

GPU

DirectX 12 compatible discrete GPU (NVIDIA / AMD / Intel Arc)

NVIDIA RTX recommended — TensorRT acceleration is available on RTX. macOS GPU requirements will ship with the Mac build.

Memory

16 GB RAM or above

Keeps previews and export staging responsive under load.

Storage

Fast SSD workspace

Better for caching, temp artifacts, and larger preview sessions.

Windows 10 (64-bit, 1809+) or Windows 11 today; macOS coming — planned minimum macOS 13+.

Frequently Asked Questions

Can it remove background noise from a video directly?

Yes. Point the denoising module at the video file itself — no need to extract the audio track first. The cleaned soundtrack is re-attached on export.

What is dereverberation?

It removes the room echo baked into recordings made in untreated spaces — hallways, conference rooms, empty apartments — so the voice sounds close and clear instead of distant and hollow.

Can I separate vocals from background music?

Yes. Vocal separation splits a mixed track into vocals and accompaniment. Use it to isolate dialog buried under music, or to extract an instrumental bed. Separation quality depends on how dense the original mix is.

Will it fix distorted or clipped audio?

Partially. Clipping destroys information at the moment of recording, so it can be softened but not fully reversed. Noise and reverb, by contrast, respond very well — preview on your own file to hear exactly what you'll get.

Is my footage uploaded to the cloud?

No. The AI processing runs on your own GPU and your media files are not uploaded — there is no queue and no per-minute cloud fee. The network is used only for sign-in and license checks (needed to export on a paid plan) and for updates.

Can I try it before buying?

Yes. Download KwaFlux and render 1-, 3-, and 5-second effect previews across all AI modules without creating an account. You only sign in and pick a paid plan when you want to export or convert, and there is a $199.99 Perpetual License if you prefer to skip subscriptions.
