Audio denoising
Strips steady background noise — hum, hiss, air conditioning, traffic bed — while keeping speech intact.
Kwaflux feature
AI audio enhancer — because half of video quality is sound
Viewers forgive soft pixels long before they forgive noisy audio. Kwaflux cleans the soundtrack in the same local pipeline that fixes the picture: background-noise removal, voice enhancement with dereverberation, and vocal separation — no separate audio app, no upload.
- Remove background noise from video or standalone audio files
- Voice enhancement with dereverberation for echoey rooms
- Separate vocals from music for dialog isolation or instrumentals

The three audio modules
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.
Audio is the quality signal people actually notice
Research on viewer behavior keeps reaching the same conclusion: audiences tolerate mediocre image quality far longer than bad sound. A crisp 4K upscale with hissy, echoey dialog still reads as amateur. That is why Kwaflux treats audio as a first-class part of the enhancement pipeline rather than someone else's problem.
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. Each maps to one of the three modules — denoise, dereverb, separate.
What AI audio cleanup 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
Import video or audio
The modules work on a video's soundtrack directly or on standalone audio files — no need to extract tracks first.
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.
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
GPU
DirectX 12 compatible discrete GPU (NVIDIA / AMD / Intel Arc)
NVIDIA RTX recommended for the best performance via TensorRT acceleration.
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 10/11 (64-bit) supported today; macOS is in development.
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. Kwaflux processes everything on your own machine — nothing is uploaded, there is no queue, and your media never leaves your computer.
Can I try it before buying?
Yes. Download Kwaflux and render 1-second and 3-second effect previews across all AI modules without creating an account. A free account plus a paid plan unlocks 5-second previews and full export, and there is a $199.99 lifetime license if you prefer to skip subscriptions.
