## Overview

This tool provides advanced audio encoding options, enabling you to convert audio files to formats like MP3, AAC, OGG, and FLAC with precise control over bitrate, sample rate, channels, and other encoder parameters.

## Inputs

- **Audio File** (file): Select an audio file
- **Output Format** (select)
- **Target Bitrate** (select)
- **Sample Rate** (select)
- **Audio Channels** (select)
- **Extra Encoder Options** (textarea): e.g., -profile:a aac_low or -application audio for Opus
- **Keep Metadata** (checkbox)

## When to use

- When you need to convert an audio file to a specific format for device or platform compatibility.
- When you want to adjust audio quality by modifying bitrate or sample rate for size or fidelity optimization.
- When you require fine-tuned encoder settings, such as extra arguments, for professional or custom audio processing.

## How it works

- Upload your audio file using the file input, supporting common audio types up to 125 MB.
- Select the desired output format from options like MP3, AAC, M4A, OGG Vorbis, Opus, or FLAC.
- Configure settings such as target bitrate, sample rate, and audio channels, or add extra encoder arguments.
- Optionally choose to keep metadata, then download the converted audio file.

## Use cases

- Converting podcast recordings from WAV to MP3 for distribution on streaming platforms.
- Optimizing audio files for web use by reducing bitrate and changing format to AAC.
- Archiving audio in lossless FLAC format while preserving original quality and metadata.
