CleanNoise is a browser-based AI denoiser that strips background noise from audio and video files while keeping voices sounding natural. It targets the steady, low-level sounds that sit behind speech — air conditioning hum, computer fans, street rumble, wind, hiss, and room tone — and separates them from the changing frequencies of the human voice. The result is a cleaner track that sounds closer to a studio recording than a raw phone capture.
How it works
You drop an audio or video file into the tool, and CleanNoise analyses the recording automatically. There is no need to select a silent section by hand or tune a filter. The AI detects the noise layer, suppresses it, and restores clarity to the voice. If a recording is echoey or muffled, an optional Remove echo / reverb setting adds extra restoration. You can compare the original and cleaned versions before committing to anything.
Try before you pay
The preview model is unusually generous for this category. CleanNoise processes your file and plays a free 30-second preview at full quality, with no sign-up and no card required. If the result works for you, the full-length download costs $0.99 per file with no account needed, or you can subscribe to CleanNoise Pro for heavier use. Files are uploaded only to produce the cleaned result and are deleted within 48 hours.
Who it is for
CleanNoise is built for people who record voice in imperfect environments:
- Podcasters removing room tone and hum between guests
- Video creators cleaning wind, traffic, and crowd noise from on-location audio
- Remote workers fixing noisy Zoom, Meet, and Teams recordings
- Students and researchers making lecture and interview recordings easier to transcribe
- Musicians reducing hiss and hum from home demos
- Support and sales teams improving call recordings for QA and training
Beyond denoising
The platform also includes companion tools for removing noise from video, extracting audio from video files, and enhancing quiet or muffled recordings. It works in any browser with no install, supports common formats including MP3, WAV, M4A, MP4, MOV, and MKV, and handles files up to an hour long.
What sets CleanNoise apart is the combination of a voice-tuned AI model, a genuinely free full-quality preview, and a pay-per-file option that avoids subscriptions or trial traps. It fits best for anyone who needs a single recording cleaned quickly and wants to hear the result before spending anything.
