Remove Background Noise from Audio Online
Clean up noisy recordings with our free noise reducer. The recommended AI mode (DeepFilterNet) is a neural denoiser that removes hiss, hum, static, and even non-steady background noise — while keeping voices natural. Prefer a classic approach? Several traditional filters are available too. Upload your file, pick a method, and download the cleaned WAV. No sign-up and no watermarks.
How to Remove Noise

- Choose a method — AI Noise Removal is recommended for most recordings.
- Process and download your clean audio (WAV).
Noise Reduction Methods
- AI Noise Removal (DeepFilterNet) – Neural denoiser; best all-round results, handles background chatter, traffic, and other non-steady noise
- Spectral Gate – Classic method for speech with steady background noise (fan, AC, hum)
- Wiener Filter – Fast, general-purpose reduction
- Median Filter – Targets clicks, pops, and crackle
- HPSS + Median – For music with vocals
Best Practices
- Clear speech – works best when the voice is louder than the noise
- Try AI first – it usually beats the classical filters, especially on uneven noise
- Better source = better result – higher-quality input cleans up more naturally
Frequently Asked Questions
The AI method (DeepFilterNet) is a neural network trained to separate speech from noise, so it removes a wider range of noise — including non-steady sounds — while keeping voices natural. The classical filters (spectral gate, Wiener, median, HPSS) are faster and work well on steady noise; try them if you prefer a lighter touch.
The AI denoiser is designed to preserve natural-sounding speech. Very noisy recordings may show slight artifacts, but the voice stays clear and intelligible.
No. This tool removes noise to make speech clearer. It does not separate overlapping speakers or strip out background music.
The result downloads as a WAV file, and you can upload audio up to 10 MB. To convert it to MP3, use our Convert Audio tool.
