Cleanaudio.io
CleanAudio processes uploaded audio and video to reduce background noise in speech recordings. Its browser-based cleanup tool is aimed at podcasts, interviews, voiceovers and other spoken material where unwanted sound distracts from the speaker.
Upload a recording and hear a preview
The site accepts common audio and video formats, including MP3, WAV, MP4 and MOV. It lists a 500MB file limit and a 60-minute duration limit. You can hear a 30-second cleaned preview without signing up or entering a credit card, then decide whether to pay for the full download.
That preview is the most useful place to assess your own recording. Choose a section with the background sound you want removed and listen for changes to the speaker's consonants, pauses and quieter words. Compare it with the original before processing a complete interview or a file you cannot re-record.
Match the tool to the noise
CleanAudio describes support for wind, fan noise, traffic, electronic hum and room echo. Those are the publisher's stated cleanup targets; the result on a particular recording depends on the material you upload.
Its workflow centers on cleaning the existing audio track. If your next task is turning the spoken content into text, Transcripto's timestamped transcription addresses that separate step. Keep the original recording and check the cleaned version before using either file for a transcript or publication.
Compare occasional and regular use
The page offers pay-as-you-go hour packs and a monthly PRO subscription. It describes PRO's unlimited cleaning as subject to a fair-use policy, so check the current limits before treating it as unrestricted processing. A free preview is distinct from a free full-length download.
CleanAudio says it deletes uploaded and processed files within 24 hours and does not use them for AI training. Confirm the current privacy terms before uploading confidential interviews or client recordings. For a first trial, use a short, non-sensitive sample that represents the noise you need to handle; listen to the output before deciding whether the service fits your editing routine.
