Overview

This tool inverts the phase of a selected audio channel, commonly used for vocal reduction when summed to mono or for creative stereo effects. Upload a stereo audio file, choose which channel to invert (left, right, or both), and export in your preferred format like MP3 or WAV.

When to use

When you need to reduce or remove vocals from a stereo audio track for karaoke or remixing purposes.
When experimenting with stereo imaging and phase effects in audio production or sound design.
When preparing audio files for mono summation to minimize phase cancellation issues in mixing.

2Select the channel to invert: left, right, or both channels.
3Choose the output format from options like MP3, AAC, WAV, or others.
4Process the file and download the resulting audio with the inverted phase.

Use cases

Creating karaoke tracks by reducing lead vocals in stereo songs for sing-along events.
Designing unique stereo effects for electronic music or audio experiments in production.
Preparing audio stems for professional mixing where phase alignment is critical for clarity.

Examples

1. Vocal Reduction for Karaoke

Background

A DJ wants to create a karaoke version of a popular song by minimizing the lead vocals in a stereo mix.

Problem

The vocals are centered in the stereo field, making them difficult to isolate without affecting other instruments.

How to use

Upload the stereo MP3 file, select 'both channels' to invert, and export as WAV for high-quality output.

channel: both, outputFormat: wav

Outcome

The processed audio has reduced vocal presence when played in mono, making it suitable for karaoke use.

2. Stereo Effect in Music Production

Background

A music producer is working on an electronic track and wants to add spatial depth to a synth line using phase manipulation.

Problem

The synth line sounds flat and lacks stereo width, affecting the overall mix's immersion.

How to use

Upload the synth audio file, invert only the right channel, and export as FLAC to maintain audio quality.

channel: right, outputFormat: flac

Can I invert both channels at the same time?

Yes, you can choose to invert the left channel, right channel, or both channels simultaneously.

What is phase inversion typically used for?

Phase inversion is often used to cancel out vocals when audio is summed to mono or to create stereo widening effects.

Will this completely remove vocals from a track?
