How to remove background noise from audio

  1. Choose an audio file, then select AI speech denoise or conventional denoise.
  2. Adjust the reduction strength or conventional settings, and choose the output format.
  3. Select Reduce Noise and follow the progress. You can cancel processing at any time.
  4. Listen to the original and processed recordings, adjust if needed, then download the result.

Reduce unwanted background sound in interviews, voice notes, podcasts and narration. Compare the original and processed audio before downloading.

AI speech denoise is designed for spoken voice. For music or recordings where you want to keep ambient sounds, choose conventional denoise and adjust its filters.

Conventional denoise offers FFT and Non-local Means, high-pass and low-pass filters, and a noise gate for quiet gaps. Start with the Light or Voice preset, then adjust while comparing the result.

AI mode produces 48 kHz mono audio. Conventional mode keeps the source channel layout. Both modes let you choose MP3, WAV, M4A, AAC, FLAC, OGG or Opus output.

Audio noise reduction FAQ

Which mode should I use for speech or music?

Use AI speech denoise for interviews, voice notes and narration. It may suppress music and ambient sounds, so choose conventional denoise when those sounds should remain.

Can I process video, and what will I download?

You can also select a video to process its audio track. The download is an audio file in your selected format. AI mode outputs 48 kHz mono; it does not export a video.

How strong should the AI reduction be?

Start at 30 dB and compare the result. The value limits how much noise can be attenuated; it is not a guaranteed reduction for every recording. Higher settings may remove more noise but can also affect quiet speech.

Are recordings uploaded?

No. Audio processing happens in your browser. AI resources are downloaded on first use and cached when browser storage is available; your recording is not uploaded.

Is there a file size or duration limit?

There is no fixed limit imposed by this tool. Available memory, file length and device performance affect processing. First use also loads the audio engines. If a large recording fails, try a shorter clip. Cancel stops processing without creating a download.
