The bridge between your digital and physical collection

TropoAudio is a free software album collection manager. Synchronize your albums from Discogs, enrich them with custom metadata, and locate your records on physical shelves with connected LED strips.

TropoAudio — Collection
TropoAudio Interface Preview

Designed for serious music collectors

A responsive, modular manager built for large vinyl and CD collections.

Custom Metadata

Enrich album entries with custom fields: exact shelf position, purchase price and simplified styles.

Physical LED Locator

Select an album, styles, or artists on the screen, and the corresponding slots on your shelf light up thanks to LED strips.

Security & API Proxy

Proxy architecture with Apache/Nginx. Personal API tokens and credentials are never exposed to client browsers.

Decoupled Architecture

A clean NPM workspace monorepo separating UI components, state management, cache, hardware drivers, and data plugins.

Portable Backups

Export and restore full collection archives with metadata and cover artwork in portable ZIP packages.

Find your records in the blink of an eye

  • Immediate visual indication of the selected album, filtered styles, or filtered artists.
  • Direct HTTP integration with lightweight ESP32 firmware.
