Adjust audio volume precisely in decibels to make quiet recordings louder
A recording that is too quiet is frustrating; one that is too loud is worse. Meicut's volume adjuster raises or lowers the loudness of any audio file with precise decibel control from -60dB to +24dB, so your music, voice memos and podcasts come out at just the right level, and it can level a whole batch of files at once.
Upload your audio, drag the slider or tap a preset, listen to the preview, and start. Batch processing works with a free account; a single file needs no sign-up.
- Precise gain control from -60dB to +24dB in 0.5dB steps

- Live preview plays the audio at the new level
- Percentage readout alongside the decibel value
- Batch processing levels a whole queue with one setting
- Works with MP3, WAV, OGG, M4A, AAC, FLAC and WMA
Common volume adjustments
Make quiet recordings audible
Voice memos recorded across a room and interviews with a soft-spoken guest often need a real lift. Start with the +5dB or +10dB preset and stop as soon as speech sits comfortably above the noise.
Bring loud audio down to a safe level
Clipped, blasting recordings are tiring to listen to. A negative gain pulls them back to a comfortable level, and the decibel readout tells you exactly how much you took off.
Level a playlist or album
Tracks from different sources rarely match in loudness. Queue them all, apply the same adjustment, and the whole set plays back at a consistent level without reaching for the volume knob.
Prepare audio for a video or presentation
Background music that drowns the narration ruins a video. Drop the music bed a few decibels before adding it, and the voice stays clearly on top.
Fine-tune by ear with the preview
Decibels are precise but ears are the judge. Play the preview after each adjustment and settle on the smallest change that sounds right, especially when boosting.
Boost or cut
Boost quiet audio
Positive gain lifts the whole file. Modest boosts stay clean; pushing a very quiet recording far also raises its background noise, so use the smallest boost that does the job.
Cut loud audio
Negative gain simply lowers the level with no side effects to worry about. If a recording is distorting because it was captured too hot, cutting will not repair the clipped peaks, but it does make it listenable.
Frequently Asked Questions
How do I make an audio file louder?
Upload your audio and set a positive gain in decibels, then start processing and download the louder version. You can adjust several files at once with the same setting.
Can I reduce the volume of audio that is too loud?
Yes. Set a negative gain to bring an overpowering recording down to a comfortable listening level.
Will boosting the volume distort my audio?
Small boosts are usually clean. If you push a quiet recording very high, some background noise may become noticeable, so use the smallest boost that gets the loudness you need.
Can I adjust the volume of several files at once?
Yes. Add multiple files, set the gain once, and every file is processed with the same adjustment. Batch processing works with a free account; a single file needs no sign-up.
What do the decibel numbers mean?
Decibels measure the change in level: positive values make the audio louder, negative values quieter. The page also shows the equivalent percentage, and the preview lets you judge by ear.
What happens to my uploaded audio?
Files are uploaded for processing, then expire and are deleted according to your account rules.
