Clean cassette transfers
Reduce steady tape hiss from digitized family recordings, old lessons, or archival speech files.
Result preview: Digitized tape audio can lose some steady hiss before it is boosted, trimmed, or archived.
Background Noise Reducer
Make old noisy recordings easier to understand.
Local processing · your file stays on your device
This local reducer works best on steady hiss or low rumble. Auto mode samples quiet moments instead of assuming the opening is silence. It cannot fully separate voices from loud music, TV, or overlapping speech.
How to use
Use the Basic Background Noise Reducer in four practical steps.
- Step 1 Load the noisy source
Choose a cassette transfer, room recording, fan-noise clip, hum-heavy lecture, or old voice file with steady background noise.
- Step 2 Set the noise reduction strength
Start gently so voices do not sound watery or damaged. Increase strength only if the noise still distracts from the content.
- Step 3 Use a noise sample from the start when possible
If the beginning contains only hiss, hum, or room tone, use that as the noise sample so the cleanup targets the right sound.
- Step 4 Preview before saving the cleaner copy
Click Prepare preview, listen to speech clarity and artifacts, then Reduce noise and download if the cleanup helps.

Best-in-class benchmark
How this tool closes the gap.
Checked against mature online audio tools for the same job: the goal is not only to complete the task, but to make the next decision obvious.
Mature cleanup tools offer presets, before-and-after thinking, safety warnings, and clear export choices for voice, music, audiobooks, or old recordings.
Many one-click cleanup tools hide what changed, so users cannot tell whether a setting is too aggressive.
Cinch frames each cleanup around listening comfort, original-file safety, practical next steps, and clear result previews that reduce overprocessing.
FAQ
Questions about the Basic Background Noise Reducer.
When should I use this free online Basic Background Noise Reducer?
Use it when you already have an audio file and need a cleaner, smaller, clearer, or easier-to-share copy before opening a full audio editor. It is useful for lecture recordings, meeting audio, voice notes, podcasts, music clips, MP3 files, WAV files, and saved browser recordings.
Does the audio file stay on my device?
Yes. This browser-based audio tool is designed to process the file locally, so you can test settings, preview the result, and download a new copy without uploading private recordings to a server.
Which audio formats work best?
Common browser-supported formats such as MP3, WAV, M4A, AAC, OGG, and FLAC usually work best. Very large files, unusual codecs, or protected streaming files may need to be converted, trimmed, or recorded again first.
What should I check before downloading the new audio?
Preview the result, compare it with the original, and make sure the speech, music, timing, volume, file size, or metadata still feels right. If the setting is too strong, choose a gentler option and run the audio processing step again.
