Speech Audio Enhancer for Free
This speech audio enhancer makes a spoken recording easier to hear when you cannot name one noise. It lowers steady noise, lets you mix the original back in, and sets the loudness. It does not master a song or change the speaker. Hear 30 seconds of the busiest stretch free, then download a WAV.

How do I compare the original and the clearer voice?
This audio enhancer makes speech easier to hear by lowering steady noise and letting you set the level. It does not master a song, and it does not turn the speaker into a different voice. Hear 30 seconds of the busiest stretch before you pay.
Original
The voice as recorded, with the hiss, hum, or room tone still under it.
Clearer
The same 30 seconds after steady noise drops. The speaker should still sound like the same person.
What makes a spoken recording hard to hear?
An audio enhancer is for speech that is hard to follow. It is not a music master, and it is not a new voice.
A quiet phone memo
The words are there, but they sit under hiss. The preview shows whether the sentence is easier to hear.
A laptop call
Fan noise and a thin voice can share one file. Keep it when the person is clearer and still recognizable.
A class recorded from the back
The lesson is usable if the voice rises above the room tone. Stop if consonants start to chirp.
A voice that is simply too low
Volume can lift the preview after the noise drops. It does not rebuild a performance.
Why choose EraseNoise as an audio enhancer
You hear the voice first. There is no equalizer, compressor, or voice changer to learn.
Speech, not a music master
Steady noise behind speech drops, then you set how much of the original stays. A song master belongs in a music editor.
The same speaker
The voice is not replaced. A clearer take that sounds like someone else is a failed take.
A WAV you can keep
The clearer take downloads as WAV. Video files are rejected on this page. Export the voice first, or use the video page when the picture must stay.
Why set the level after you hear it?
The Noise reduction control mixes the original back in. Volume sets how loud the file you save will be.
Noise reduction
Leave it high when the hiss should drop. Pull it down if the voice turns thin. The mix is applied when you download.
Volume
Raise a quiet memo after the noise drops. This is loudness, not a new recording.
Which files can this audio enhancer take?
Upload a voice recording. This page does not accept video, and it does not enhance a finished song.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
The clearer take downloads as WAV. A camera clip needs its voice track exported first.
Speech is the source
A memo, a call, or a lesson can be the file. A stereo mix of a song is the wrong job.

Compare 30 seconds
Play the original and the clearer voice. No account is needed. Set Noise reduction and Volume only after the speaker still sounds like themselves.

Download the WAV
Keep the file when the words are easier to hear. The download is one WAV of the same person.
Where an audio enhancer fits
A phone memo you need to replay
Hiss sits under a quiet note. Enhance the speech, then raise Volume if the words are still soft.
A remote interview
The guest is hard to follow over a laptop fan. Keep the WAV when the guest is clearer and still recognizable.
A lesson recorded in a classroom
Room tone covers the teacher. Use this audio enhancer when the goal is intelligibility, not a studio mix.
When is clarity the real problem?
Use this audio enhancer when speech is hard to hear and you want to set the level. Name a different problem and use the matching page.

Frequently asked questions
How do I enhance audio online?
Upload a spoken recording and compare 30 seconds. Set Noise reduction if the voice turns thin, and Volume if the memo is still quiet. Download the WAV only if the same person is easier to hear.
Is an audio enhancer a music mastering tool?
No. This page lowers steady noise under speech and lets you set the level. It does not equalize a song, compress a mix, or master music.
Does enhance mean a voice changer?
No. The speaker stays the same person. If the clearer preview sounds like someone else, do not download it.
How is this different from removing background noise?
Both lower steady noise behind speech. Use the noise page when you can name wind, a fan, traffic, or hum. Use this page when the voice is simply hard to hear and you want to set how much of the original stays and how loud the file is.
What do Noise reduction and Volume change?
Noise reduction mixes the original recording back into the cleaned voice. Lower it if the words turn thin. Volume sets the loudness of the file you save. Neither control writes a new performance.
How many free previews do I get, and how large can the file be?
You can hear the 30-second preview 3 times in 24 hours without an account, and 20 times in 24 hours after you sign in. The upload limit is 2 GB. The full file is billed in whole minutes, rounded up, with a minimum of 1 minute. Video files are rejected on this page.
