Frequently asked questions

Can I remove background noise from a video?

Yes. Upload a video and download it with cleaner speech. Compatible video tracks are preserved without re-encoding.

Does FuzzPuppy upload my file?

No. Noise removal runs locally in your browser.

What background noise can it remove?

It works on wind, traffic, fans, crowds, machinery, and room noise. Results vary when noise is louder than the speaker or several people talk at once.

Can I clean recordings longer than one minute?

Yes, when your browser supports streaming audio processing and local file storage. We check support automatically. Other browsers or unsupported file formats are limited to 60 seconds; try a current desktop browser for longer recordings. Keep the tab open and visible while processing.
