  description

  SVA is an unofficial, independent real-time audio visualizer that works with playback audio on the Suno website and displays visualization in a Chrome side panel.
  
  Designed for music creators and producers who want to monitor loudness, peaks, spectrum balance, and stereo characteristics in real time.
  
  Features:
  • LUFS measurement (Momentary, Short-Term, Integrated) — based on ITU-R BS.1770-4
  • True Peak detection with peak hold
  • Loudness Range (LRA) and Dynamics
  • Frequency Spectrum (LO / MID / HI-MID / HI)
  • Goniometer (stereo phase visualization) with Correlation bar, histogram, and phase warning
  • Panel copy — captures the side panel as a PNG to clipboard (⧉ button)
  • Loudness History graph
  • Session-based Snapshot comparison (up to 10)
  • Japanese / English tooltip support
  
  How to Use:
  1. Open the Suno website in Chrome
  2. Click the SVA icon to open the side panel
  3. Play a track — audio visualization starts automatically
  4. Use SNAPSHOT to temporarily save and compare measurements during the current session
  
  Privacy:
  • All audio processing is performed locally in the browser
  • Audio data is not recorded, uploaded, transmitted, or shared
  • Snapshots are stored in memory only and are cleared when the panel is closed
  • Only the UI language preference is saved locally using localStorage
  • No personally identifiable information (PII) is collected
  • The copy button captures the panel display as a local PNG image and writes it to your clipboard. No image or metadata is transmitted externally.
  
  Notes:
  • Works with the Suno player only. Editor and Studio are not supported.
  • This is an unofficial tool and is not affiliated with, endorsed by, or sponsored by Suno, Inc.
  • "Suno" is a trademark or registered trademark of Suno, Inc.
  
  Version History:
  
  v1.3.0
  • Added Correlation histogram — shows stereo/mono trend accumulated over the current track
  • Added phase warning indicator — red line appears at the bottom of the Correlation bar if phase inversion is detected
  
  v1.2.9
  • Added panel copy button (⧉) — copies the entire panel as a PNG to clipboard
  • Improved Correlation display: vertical bar overlaid on Goniometer canvas
  • Unified hover colors for header buttons
  
  v1.2.8
  • Fixed stability issues when opening and closing the side panel rapidly
  • Improved reliability of analysis stop/start control
  
  v1.2.7
  • Improved True Peak accuracy with 4x oversampling (ITU-R BS.1770-4 compliant)
  • Improved LRA accuracy with EBU R128 gating
  • Reduced CPU usage when side panel is not open
  • Fixed auto-reconnect after manual STOP
  • Fixed duplicate song-change events on long sessions
  
  v1.2.6
  • CLR button now requires confirmation before clearing all snapshots
  • Memo input now appears as a title on the snapshot card
  • All tooltips unified with custom JP/EN tooltip system
