How to use Audio Peak Limiter

Choose an audio file.
Adjust the tool-specific controls, then select the main action button.
Review the measured result, listen to the preview, and download the new file if useful.

What this audio tool does

The limiter detects the required gain for each sample, applies fast attack and configurable release smoothing, then exports the limited audio as WAV.

Gain reduction follows the loudest channel so stereo balance stays intact; a ceiling below 0 dBFS leaves headroom.

This is a practical peak limiter, not a mastering-grade true-peak or loudness compliance processor.

Supported formats and limits

Input decoding depends on Web Audio support in the current browser. Output is WAV unless this converter explicitly uses a browser-verified MediaRecorder codec.

Example and practical tips

Try audio peak limiter on a short copy first, listen for artifacts, and then process the full recording. Cleaner input produces easier-to-read results.

Close other audio-heavy tabs while processing.
Keep the source file until you have checked the download.
Reset before testing a different recording.

Frequently asked questions

What ceiling should I use for an audio peak limiter?

Audio Peak Limiter uses the option shown above and real decoded audio data, so the best setting depends on the recording rather than a fixed preset.

Does limiting make quiet audio louder?

Browser audio capabilities vary. The page checks the required decoder or encoder and shows a specific error when it is unavailable.

How does release time affect pumping?

The calculation is based on samples from the selected or recorded audio, not on the filename or a simulated result.

Can a peak limiter repair existing clipping?

Processing stays in this browser tab. Object URLs and decoded buffers are released when you reset or leave the page.

Is this a true-peak limiter?

Use a clean source, preview the result, and adjust the available controls if the first pass is not a good fit.
