EraseNoise for cleaning recorded audio and video

EraseNoise reduces background noise in an audio or video file you have already recorded. The publisher describes examples with wind, street traffic and fans. You can compare the original and cleaned audio in a 30-second preview before deciding whether to process the recording.

Listen for what happens to the voice

Pick a section where the noise is audible while someone is speaking. Switch between the original and cleaned versions and pay attention to the speech as well as the background. A quieter room tone is useful only if the words still sound natural enough for the finished recording. The publisher provides samples you can play before uploading your own file, including recordings with a fan or street noise.

Check the format you need for editing

The site lists common audio and video inputs including MP3, WAV, MP4 and MOV, with a 2 GB upload limit. Audio downloads as WAV, and video downloads as MP4 with a cleaned soundtrack. If you plan to use the result in an edit, compare the sound with the original before replacing any tracks. Check sections where the speaker moves or the background changes because the same recording can contain several different noise conditions.

Review the preview and download allowance

The publisher offers a free 30-second preview and says a new account can download one cleaned minute. For a longer recording, that free download is an excerpt. Paid processing rounds each file up to a whole minute. Check the duration before processing a batch, especially if it contains many short clips. EraseNoise also offers a separate browser tool for removing long silences.
