## Overview

The Audio Dynamic Range Report tool analyzes an audio file to measure its dynamic range, providing a detailed JSON report on the variation between peak and RMS levels for audio quality assessment.

## Inputs

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

## When to use

- When evaluating loudness variation in audio recordings for mastering or production.
- To ensure consistent audio levels in podcasts, broadcasts, or streaming content.
- For comparing dynamic range across different audio files or formats during quality checks.

## How it works

- Upload an audio file in a supported format such as MP3, WAV, or FLAC.
- The tool processes the file using audio analysis algorithms to calculate dynamic range metrics.
- A JSON report is generated with key data including peak amplitude, RMS level, and dynamic range in decibels.

## Use cases

- Mastering engineers analyzing music tracks for optimal loudness in production.
- Podcast editors ensuring audio consistency across episodes before publishing.
- Audio archivists assessing the quality and dynamic range of historical recordings.

## Frequently asked questions

### What is dynamic range in audio?

Dynamic range is the difference in decibels between the quietest and loudest parts of an audio file.

### What audio formats are supported?

The tool supports common audio formats under the audio/* category, like MP3, WAV, and FLAC.

### How accurate is the dynamic range analysis?

The analysis uses standard audio statistics algorithms to provide reliable measurements based on the input file.

### Can I analyze large audio files?

Yes, the tool supports files up to 200MB in size.

### What does the JSON report include?

The report includes metrics such as peak level, RMS level, and the calculated dynamic range value.
