Make a voice recording clearer: this AI voice enhancer keeps your voice as it was recorded and pulls down everything behind it. Room noise, fans, traffic, hum and hiss go into the background. No sign-up, no watermark, 10 recordings a day.
Voice memo, call, interview, lecture or video: MP3, WAV, M4A, FLAC, OGG or MP4, up to 45 minutes. You get a cleaned MP3 and a lossless WAV back.
No watermark, no sign-up, 10 recordings a day. Files up to 45 minutes free. A pass allows longer files and adds loudness levelling and a heavier repair pass for rough recordings.
A voice sounds unclear when it competes with the sound around it. Turn that layer down and the same voice reads as closer and easier to follow. That is all this voice enhancer does, and on the free tier it does it without touching the voice itself.
So it is not a voice changer, it does not make you sound like a studio announcer, and it cannot bring back words that were drowned out or distorted when you recorded them. For music, use StemGrab; this model is tuned for speech.

|---|---|---|---|

| Free monthly pass (email) | 2 hours | 25 | yes |
| ShinobiTools pass | 3 hours | 50 | yes |
No watermark on any tier. Your upload is deleted right after processing and the result is wiped within 45 minutes.
Mostly music, or several sources mixed together? The broader audio enhancer page explains what the same tool can and cannot do there. Want a written transcript of the cleaned recording? ScribeGrab turns speech into text.
Yes. A trained model separates your voice from the sound behind it and pulls the background down. On the free tier your voice is not replaced or re-generated; the deeper cleanup that comes with a pass rebuilds it, for recordings with echo or heavy noise.
No, it is not a voice changer. Pitch and tone stay as recorded; only the noise around the voice is reduced. If the voice starts to sound thin, the recording was probably very noisy to begin with.
Yes: 10 recordings a day, up to 45 minutes each, with no sign-up and no watermark. A pass allows longer files and adds loudness levelling.
Yes. Upload the M4A as it is. MP3, WAV, FLAC, OGG and video files work too, up to 1 GB.
Not on the free tier. It makes the voice clearer by removing what is behind it, not by boosting the level. Loudness levelling to podcast level comes with a pass.
The upload is deleted right after processing and the cleaned file is wiped within 45 minutes. See privacy.
