About this tool
Normalize audio levels without uploading the file
Audio normalization adjusts the overall gain so that the highest peak reaches a selected target level. It can make quiet recordings easier to hear and create more consistent output.
Normalization is useful for interviews, voice notes, podcast clips, music previews and batches of recordings captured at different levels.
AudioDock performs the calculation locally and does not require a remote processing queue.

Frequently asked questions
Is normalization the same as compression?
No. Normalization changes overall gain, while dynamic compression reduces the difference between louder and quieter parts.
What target peak should I use?
A target near -1 dB is commonly used to leave a small amount of headroom.
Does AudioDock upload the recording?
No. Normalization runs locally in your browser.
