Remove Background Noise from Audio — AI-Powered, Free
Upload any audio file and remove unwanted background noise in seconds. This tool uses browser-based RNNoise neural speech denoising to reduce steady background sound while preserving spoken voice. Adjustable noise reduction strength lets you balance between maximum noise removal and natural sound. All processing happens in your browser — your audio files are never uploaded to any server. Supports MP3, WAV, OGG, FLAC, and most common formats, with MP3 and WAV downloads.
Remove Background Noise from Voice Recordings and MP3 Files
Upload a podcast, interview, voice memo, call recording, or other spoken audio and reduce fan noise, AC hum, hiss, keyboard sounds, and room ambience with browser-based neural speech denoising. Adjust the cleanup strength, compare the original and cleaned audio at the same point, then save the result as a smaller MP3 or an uncompressed WAV. The denoising model runs in your browser, and your recording is not uploaded for processing. This speech-first mode works best when the voice is the sound you want to keep.
Frequently asked questions
How does online noise removal work?
The tool uses an RNNoise neural speech-denoising model in your browser. It analyzes short frames of the recording to reduce background noise while keeping spoken voice, then blends the cleaned signal with the original according to the strength you choose. Your audio is not uploaded for processing.
Will it affect voice quality?
Light noise removal preserves voice quality well. Higher settings may introduce subtle artifacts but will dramatically reduce noise. Preview before downloading to find the right balance.
What types of noise can it remove?
Background hum, fan noise, AC noise, traffic sounds, keyboard clicks, and general room ambience. It works best on consistent, steady noise rather than sudden loud sounds.
