Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How does the Audio & Video Noise Remover work client-side?
We use the Web Audio API to decode the audio track of your uploaded file into an in-memory floating-point buffer. We then execute a multi-band noise gating DSP filter that divides the frequencies into low, mid, and high bands to isolate and attenuate background hums, wind rumble, and static hiss locally.
Does this tool support video files as well?
Yes! You can upload video files (MP4, WebM, MOV). The tool extracts the audio track, processes it to remove noise, renders the video frames onto a canvas, and compiles the clean audio and video tracks back together in your browser.
Are my media uploads secure and private?
Absolutely. The entire noise removal and video re-rendering process is run offline in your browser memory (RAM). Your audio and video files are never transmitted to any external server, guaranteeing 100% data privacy.
