About this tool
Need online noise removal without installing software? This free Audio Noise Remover lets you remove background noise from audio online in your browser. Upload an MP3, WAV, M4A, AAC, OGG, FLAC or OPUS file and choose a mode. Voice mode uses RNNoise, a small neural network designed to separate speech from noise, followed by gentle spectral clean-up, which suits calls, voice notes, lectures and podcasts. General mode uses FFmpeg's FFT-based noise reduction for music and mixed audio. Both remove low rumble. Pick light, medium or strong, compare before and after, then download MP3 or WAV. Strong settings remove more noise but can make voices thinner.
Good to know
- Voice mode is designed for speech and may suppress music or singing.
- Very noisy recordings can sound processed at strong settings.
Frequently asked questions
Is this online noise removal tool free?
Yes. It runs online with nothing to install. Like our other free tools, it has a daily free-use limit.
Which mode should I use to remove background noise from audio?
Voice for speech: calls, voice notes, lectures and podcasts. General for music or mixed content, because the voice model can suppress non-speech sounds.
Can it remove all noise?
No. Constant noise such as hiss and fans reduces well; sudden sounds, overlapping voices and heavy echo are much harder. Your file is processed in a private temporary folder and deleted once the result is sent back.
Is Audio Noise Remover private?
Your file is uploaded over an encrypted connection and processed in a private temporary folder on our server. The uploaded file and the result are deleted from the server as soon as processing finishes — whether it succeeds or fails — and the result is sent straight to your browser. If an upload is interrupted part-way, its temporary data is removed automatically within about 30 minutes. We do not keep copies.
