## Overview

Renders a vectorscope image using FFmpeg avectorscope (lissajous mode).

## Inputs

- **Audio File** (file): Select an audio file
- **Image Width** (text): e.g., 600
- **Image Height** (text): e.g., 600
- **Draw Mode** (select)
- **Amplitude Scale** (select)
- **Zoom** (number)
- **Start Time (seconds)** (number): Leave empty for auto-detection

## 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.

## Frequently asked questions

### 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.
