Overview

The Audio Vectorscope tool generates a Lissajous vectorscope image from stereo audio files, visualizing stereo imaging and phase relationships for analysis and troubleshooting.

When to Use

  • •When analyzing the stereo field and phase correlation of audio recordings.
  • •To detect phase issues or ensure mono compatibility in audio mixes.
  • •For educational demonstrations of stereo audio principles.

How It Works

  • •Upload a stereo audio file in a supported format such as MP3 or WAV.
  • •Adjust optional parameters like image dimensions, draw mode, and amplitude scale.
  • •The tool uses FFmpeg's avectorscope filter in lissajous mode to generate the vectorscope.
  • •Download the resulting image file for review.

Use Cases

Audio engineers visualizing stereo balance in music production.
Podcast editors checking phase alignment in multi-microphone recordings.
Students and educators demonstrating audio signal concepts.

Examples

1. Visualize Stereo Spread in a Music Mix

Background
A sound engineer is finalizing a stereo mix and wants to ensure wide stereo imaging.
Problem
Need to confirm that the audio has appropriate stereo width without phase issues.
How to Use
Upload the mixed audio file, set image size to 1024x1024, and use 'line' draw mode for detailed view.
Outcome
The vectorscope image shows a wide pattern, indicating good stereo spread, helping in mix adjustments.

2. Check Phase Correlation for Podcast Audio

Podcast Producer
Background
Recording a podcast with multiple hosts using separate microphones.
Problem
Ensure that the audio channels are phase-aligned to prevent cancellation when played in mono.
How to Use
Upload the raw audio recording, use default settings, and analyze the vectorscope output.
Outcome
The vectorscope reveals any phase discrepancies, allowing for corrective editing before publishing.

FAQ

What audio file formats are supported?

The tool supports common audio formats like MP3, WAV, and others as indicated by the audio file input.

Can I change the size of the output image?

Yes, you can specify the width and height in pixels, with defaults of 600x600.

What does the vectorscope display?

It displays a Lissajous figure showing the relationship between left and right audio channels.

Is there a file size limit?

Yes, audio files must be under 200 MB based on the file limit setting.

How is the amplitude scaled in the visualization?

You can choose from linear, square root, cube root, or logarithmic scaling options.
