Overview

The Audio Channel Resample tool lets you change the number of audio channels in your files, converting between mono and stereo while preserving the original format. It's designed for quick adjustments to suit different playback environments or platform requirements.

When to use

When you need to convert stereo audio to mono to reduce file size or ensure compatibility with mono playback systems.
When you want to upmix mono audio to stereo for a richer listening experience on stereo devices.
When preparing audio files for specific platforms or devices that require a certain channel configuration, such as streaming services or mobile apps.

How it works

1Upload your audio file in a supported format like MP3, WAV, or AAC.
2Select the target number of channels: mono (1 channel) or stereo (2 channels).
3Optionally, choose a sample rate (auto, 44.1 kHz, or 48 kHz) and decide whether to keep metadata.
4The tool processes the file and provides a download link for the converted audio.

Use cases

Podcast editing: Convert stereo recordings to mono for voice-only content to simplify distribution.
Music production: Ensure audio tracks are in stereo for optimal mixing and playback on home systems.
App development: Test audio files in both mono and stereo to verify compatibility across devices.

Examples

Problem

Manually converting stereo to mono is tedious and risks losing metadata like episode titles.

How to use

Upload the stereo MP3 file, select 'Mono (1 channel)' for target channels, and keep metadata enabled.

channels: 1, sampleRate: auto, keepMetadata: true

Outcome

A mono version of the podcast is generated with all metadata intact, ready for platform upload.

2. Upmix Mono Music for Stereo Playback

Musician

Background

Problem

Upload the mono WAV file, select 'Stereo (2 channels)' for target channels, and set sample rate to 48 kHz for high quality.
