## Overview

Convert an AAC audio file to MP3 with selectable bitrate, sample rate, channel count, and optional metadata preservation.

- **Sample Rate** (select): Output sample rate
- **Audio Channels** (select): Select output channel count
- **Keep Metadata (when available)** (checkbox): Preserve title/artist tags when possible

## When to use

- Create an MP3 version of an AAC audio file for broader playback compatibility.
- Reduce or adjust MP3 output size by choosing a bitrate from 128 to 320 kbps.
- Convert stereo audio to mono or set a specific sample rate such as 44.1 kHz or 48 kHz.

## How it works

- Upload one AAC audio file.
- Choose the target MP3 bitrate, sample rate, and channel count, or keep the original settings where available.
