## Overview

Uses ffprobe to return precise length (seconds, milliseconds, and formatted time) plus per-stream timing info.

## Inputs

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

## When to use

- When you need to verify an audio file's duration before uploading to platforms with time limits.
- When editing audio and require precise timing for synchronization with other media.
- When cataloging audio files and want to include accurate duration metadata.

## How it works

- Upload your audio file using the file input field.
- The tool processes the file with ffprobe to extract duration data.
- Results are displayed in JSON format, showing total duration and stream-specific timings.
- You can copy or use the JSON output for further processing or reference.

## Use cases

- Podcast producers checking episode lengths to meet hosting platform requirements.
- Music producers verifying track durations for album compilations or streaming services.
- Audio engineers ensuring files meet specific timing standards for broadcasts or edits.
