Audio cleaner
An audio cleaner helps you review the whole recording when background noise and uneven volume distract from speech. Upload your file, compare the original with the processed sample, and listen to quiet and loud passages. Any 30 seconds you select is free without registration.

Hear the audio cleaner across a spoken passage
Judge the processed sample by the flow of the recording, including quieter words and the pauses between speakers.
Compare nearby and more distant speakers in the processed sample against the original, keeping playback volume steady so you can judge quieter replies as well as the louder introduction.
Compare a lesson in the processed sample with the original, listening for reduced room noise and more even speech volume as the teacher switches between explaining and reading notes.

Why a recording sounds uneven before processing
The tool deals with the captured sound, so microphone placement and the room still matter.
The speaker moves around
Leaning back or turning away can change how much voice reaches the microphone. Try the audio cleaner on a normal passage and compare the quieter phrase with the original.
Background sound fills the gaps
A fan can become more noticeable between sentences or beneath a softer reply. An audio cleaner gives you a processed sample to hear alongside the original conversation.
Voices arrive at different levels
A shared microphone may capture nearby and distant speakers differently. Use the processed sample to check the quieter person, and do not assume missing speech can be restored.
What to listen for in the processed sample
Use this listening checklist to review background sound and volume together rather than concentrating on an empty pause.
Fan noise
Try the audio cleaner on a quiet explanation with ventilation behind it. Compare the background and the speaker before deciding whether the processed version suits the lesson.
Electrical hum
A hum may run beneath every sentence. Listen to the processed sample during both speech and silence, then check the recording setup before the next take.
Keyboard taps
Taps can be much louder than a soft voice. Use the audio cleaner to compare the words around them, especially when someone speaks while taking notes.
Road sound
Traffic may come and go while the speaker stays at the same level. Compare a whole sentence in the audio cleaner so you hear the voice on either side of the interruption.
Room movement
A chair scrape or desk knock can distract from a reply. Try the audio cleaner on that passage and consider a fresh take if the sound covered a word.
Uneven speech volume
A quiet answer after a loud introduction can make a recording awkward to follow. Compare the audio cleaner preview without reaching for the volume control between those passages.
An audio cleaner or a manual edit
Manual editing lets you work on individual passages; an audio cleaner gives you an AI cleanup preview to assess first.
Reducing background sound
Manual: choose a noise treatment and adjust it by ear.
VoiceEnhancer: let the audio cleaner handle noise reduction, then listen to the selected passage beside the original.
Reviewing volume
Manual: adjust louder and quieter passages as part of the edit.
VoiceEnhancer: use the audio cleaner comparison to assess more even volume along with the background sound.
Checking a conversation
Manual: move through the recording and review each change.
VoiceEnhancer: begin with the free preview, paying attention to the softest contribution it contains.
Keeping a finished version
Manual: export the edit you have reviewed.
VoiceEnhancer: see pricing for full processing and downloading when the audio cleaner preview fits the recording you need.
Recordings to try with noise and volume cleanup
Choose a sample with the changes in voice level you want to assess, as well as the noise you want to reduce.
Meeting discussions
A shared recorder often hears the nearest person most clearly. Try the audio cleaner on an exchange with a quieter participant and compare the replies without changing playback volume.
Interview conversations
A guest may begin softly and become louder as the answer develops. Use the processed sample to hear that change in context rather than judging a single word.
Recorded teaching
An explanation may include reading, speaking toward the screen and turning to notes. Compare the audio cleaner result with the original before deciding about the complete lesson.
Video voice tracks
For MP4 or MOV, VoiceEnhancer extracts the audio track, processes it and combines it with the unchanged picture. Review the audio cleaner result with the scene it belongs to.
Use the audio cleaner in three steps
Keep the original and use the processed preview as a listening comparison before you continue.
Choose the recording
Upload MP3, WAV or M4A audio, or MP4 and MOV video. Select any 30 seconds for the free preview, choosing a passage that contains a useful example of the speech.
Compare the whole passage
Let the audio cleaner process your selected passage. Listen for noise reduction and more even volume, and check that quiet words still sound like the speaker in the original.
Continue to full processing
Preview without registration. Full processing and downloading require payment; see pricing if you want to use the audio cleaner beyond the selected sample.
Capture consistent sound before you process a recording
Cleanup is easier to judge when the original already contains clear speech at a reasonably consistent level.
Keep the speaking distance steady
Place the microphone where the speaker can stay comfortable. If you need to turn toward notes, move the notes rather than repeatedly speaking away from the microphone.
Check every speaker
Make a test with the people who will take part. Listen to the quietest person and move the microphone if necessary before recording the full conversation.
Leave room for louder speech
Check a naturally louder sentence in the test. If the original sounds harsh or broken up, adjust the recording setup; an audio cleaner is not a reliable repair for missing detail.
Compare at one listening level
When reviewing the processed sample, keep playback volume similar for both versions. A louder result can seem clearer at first even when a quiet word is still difficult to hear.
FAQ
What does an audio cleaner clean?
The tool focuses on background noise and more even volume across spoken audio. Compare the preview with your original and check a complete passage rather than judging only a quiet gap.
Can I try the audio cleaner for free?
Yes. Process and compare any 30 seconds you select without registration. Full processing and downloading require payment; see pricing for the current terms before continuing.
Which audio and video files does this tool support?
Upload MP3, WAV or M4A audio, or MP4 and MOV video. For a video, the processed audio track is combined with the picture again.
Is noise and volume cleanup the same as making a file louder?
This page covers noise reduction and more even speech volume. Judge the voice throughout the preview; making everything louder by itself can also make unwanted sound more noticeable.
Can the audio cleaner fix a distant speaker?
Try the preview and listen closely to the quieter person. It cannot reliably replace words the microphone missed, so a closer recording position is a better starting point.
Can I upload a recording saved on my phone?
Choose a supported file saved on the phone and compare a passage you select. Keep a copy of the original and use familiar headphones to judge the change.
How long does the site keep my uploaded files?
Uploaded files are automatically deleted within 24 hours. Keep the original and any downloaded version you need rather than relying on the upload for storage.
Can I use this tool for room reverberation?
Echo reduction is still being connected. Check availability before relying on it; the echo page also explains room setup changes that can reduce reflections during recording.
