Stereo Meter
A fascinating visualization tool that lets you see how your music creates a sense of space through stereo sound. Watch how different instruments and sounds move between your speakers or headphones, adding an exciting visual dimension to your listening experience.
Visualization Guide
- Diamond Display - The main window where the music comes to life:
- Center: Very quiet moments or moments where the combined signal is near zero
- Top/Bottom: Sound shared by left and right channels, such as centered or mono-like content
- Left/Right: Difference or out-of-phase content between the channels
- Sounds that are much stronger on one side can appear toward the labeled corners
- Green dots dance with the current music
- White line traces the musical peaks
- Correlation Bar (Left side)
- Shows left/right channel correlation
- Top (+1.0): Left and right are nearly the same, often sounding centered
- Middle (0.0): Weak channel relationship, often from wide ambience or unrelated left/right content
- Bottom (-1.0): Left and right are nearly opposite polarity, which can sound weak on speakers
- Balance Bar (Bottom)
- Shows if one speaker is louder than the other
- Center: Music equally loud in both speakers
- Left/Right: Music stronger in one speaker
- Numbers show how much louder in decibels (dB)
What You Can See
- Centered Sound: Strong vertical movement in the middle
- Spacious Sound: Activity spread wide across the display
- Special Effects: Interesting patterns in the corners
- Speaker Balance: Where the bottom bar points
- Channel Correlation: What the left correlation bar shows
Parameters
- Window (10-1000 ms) - How much recent audio is shown in the display
- Lower values: See quick musical changes
- Higher values: See overall sound patterns
- Default: 100 ms works well for most music
Enjoying Your Music
- Watch Different Styles
- Classical music often shows gentle, balanced patterns
- Electronic music might create wild, spreading designs
- Live recordings can show natural room movement
- Discover Sound Qualities
- See how different albums use stereo effects
- Notice how some songs feel wider than others
- Observe how instruments move between speakers
- Enhance Your Experience
- Try different headphones to see how they show stereo
- Compare old and new recordings of your favorite songs
- Watch how different listening positions change the display
Remember: These tools are meant to enhance your enjoyment of music by adding a visual dimension to your listening experience. Have fun exploring and discovering new ways to see your favorite music!
