Tool usage guide
The Audio Vectorscope tool generates a Lissajous vectorscope image from stereo audio files, visualizing stereo imaging and phase relationships for analysis and troubleshooting.
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.
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.
The tool supports common audio formats like MP3, WAV, and others as indicated by the audio file input.
Yes, you can specify the width and height in pixels, with defaults of 600x600.
It displays a Lissajous figure showing the relationship between left and right audio channels.
Yes, audio files must be under 200 MB based on the file limit setting.
You can choose from linear, square root, cube root, or logarithmic scaling options.
