## Overview

Audio Channel Resample changes an audio file between mono and stereo while keeping its original format. Choose the target channel count, optionally set a 44.1 kHz or 48 kHz sample rate, and decide whether to keep metadata.

## Inputs

- **Audio File** (file): Select an audio file
- **Target Channels** (select)
- **Sample Rate (optional)** (select)
- **Keep Metadata** (checkbox)

## When to use

- Convert a stereo recording to mono for voice-focused playback or simpler channel requirements.
- Change a mono file to stereo when a two-channel output is required.
- Adjust the sample rate to 44.1 kHz or 48 kHz while changing the channel configuration.

## How it works

- Upload one supported audio file, such as MP3, AAC, M4A, OGG, Opus, FLAC, or WAV.
- Select Mono or Stereo as the target channel setting.
- Keep the original sample rate or choose 44.1 kHz or 48 kHz.
- Choose whether to preserve the file metadata, then generate the converted audio file.

## Use cases

- Prepare stereo recordings as mono files for voice playback and single-channel workflows.
- Create stereo versions of mono audio when a two-channel file is needed.
- Standardize audio sample rates at 44.1 kHz or 48 kHz while retaining the source format.
