Unofficial Suno visualizer (Player/Studio/Editor). LUFS, True Peak, Spectrum & Goniometer in a side panel. No external data sent. 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 • Key detection — always-visible strip showing Key, candidates, and stability • BPM estimation and beat indicator • 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 • PLAYER mode — per-track measurement • STUDIO mode — measures Suno Studio and Editor playback in real time as one continuous session, with a rolling Loudness History (10 s–10 min, pan/zoom, overview minimap) 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 5. To measure Suno Studio or the Editor, open it and switch the mode button to STUDIO (connects automatically) 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 and a first-run guide flag are 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, Studio, and Editor. • After updating the extension, reload the Suno tab once before measuring. • Suno Studio is a Premier-plan, desktop-only feature (it will not appear if the browser window is too narrow). • 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.
