## Overview

The Audio Peak Detector analyzes audio files to identify the highest volume level, helping ensure audio quality and compliance with standards like broadcast loudness limits.

## Inputs

- **Audio File** (file): Select an audio file

## When to use

- When checking audio files for clipping or distortion before publishing.
- During audio editing to normalize volume levels across tracks.
- When preparing audio for platforms with strict loudness requirements.

## How it works

- Upload an audio file in a supported format such as MP3 or WAV.
- The tool scans the audio waveform to detect the peak volume level.
- Results are output in JSON format, displaying the peak value in decibels.

## Use cases

- Podcast production: Ensuring episodes have consistent volume without peaks.
- Music mastering: Identifying clipping in audio tracks before distribution.
- Audio engineering: Analyzing recordings for peak events in sound design.

## Frequently asked questions

### What audio formats are supported?

Common formats like MP3, WAV, and AAC are supported, based on the audio/* file type.

### How is peak volume measured?

Peak volume is measured in decibels relative to full scale (dBFS).

### Is there a file size limit?

Yes, the maximum file size is 200 MB.

### Can I process multiple files at once?

No, the tool processes one audio file at a time.

### What does the JSON output include?

The JSON output contains the peak volume level and related metadata for analysis.
