1.4.0 - Introducing Output Routing (BETA)

A new continuous audio transport system for remote playback.

Zenteek can now stream audio in parallel to AirPlay and DLNA/UPnP receivers using the new Output Routing engine. Unlike traditional renderer-based playback, audio is mixed and processed locally first, then distributed as one continuous synchronized stream to your receivers/speakers.

New

  • Per-device delay compensation
  • Per-device stream gain control
  • Optional local output mute while remote outputs continue playing
  • Added AirPlay 2 receiver pairing flow
  • Added DLNA/UPnP renderer discovery and streaming
  • Added continuous transport bus architecture for smoother transitions and crossfades

Architecture

  • Track changes, seeks and crossfades are handled locally inside Zenteek
  • Remote devices behave as audio endpoints rather than independent players
  • Greatly improved transition smoothness and multi-device consistency

Notes

  • Output Routing is currently released as BETA as i have limited hardware options to test.
  • Hardware compatibility may vary depending on the receiver implementation. (Looking at you, Samsung)
  • Some devices may require manual delay adjustment for synchronization
  • SOURCES Added support for UPnP/DLNA, including Plex-specific DLNA implementations.
  • SOURCES Added support for Lyrion Media Server (LMS).
  • UI HomeView now displays all sections instead of trying to be overly smart. Full control is back in your hands.
  • UI The HomeView welcome screen now includes the new source picker and all remote server options.
  • CORE Added automatic database backups, configurable in the Settings menu. Better to have them than need them.
  • CORE Added a launch-crash detector. If the app refuses to open for some reason, it now presents a recovery menu.
  • PLAYBACK Seek in intervals using CMD+SHIFT+LEFT or CMD+SHIFT+RIGHT (tap or hold).
  • PLAYBACK Set your preferred seek interval in the Settings menu (5s, 10s, 20s or 30s).
  • UI You can now also seek by holding down the mouse button on the "Previous Track" and "Next Track" toolbar controls.
  • UI The Back button (<) is now easier to click. The clickable area has been enlarged for better usability.
  • BUGFIX Embedded FLAC artwork is now imported correctly. The system previously detected a false positive.
  • CORE Upgraded the File Indexer architecture to support multiple types
  • CORE Enhanced the Playback Engine to resolve the best possible match.
  • CORE PlaybackEngine now accepts HTTP Streams to support remote media servers
  • SOURCES Added support for Subsonic/Navidrome

  • BUGFIX Track Context Menu: Filtered "Mixtape"-Playlist from the submenu since those lists are usually considered "archived".

Zenteek launches in May 2026. Join the waitlist on the homepage for early access and special launch pricing.

  • Album Artwork management (right click > select from disk, search online & remove from cache)
  • Artist Image management (right click > select from disk, search online & remove from cache)
  • Indexer: Simply drop "cover.jpg" or "folder.jpg" into an album folder for it to be picked up immedietly with "auto-scan" enabled.

Note: when you have enrichment enable, and try to remove a cover/artist-image, it might get pulled from server immediately again. So while enrichment is on, you can't really have "empty cover" items, even if you force delete. This is not a bug, its a feature. :)

  • New Output Tools: High-end DACs use reconstruction filters to eliminate ringing artifacts around transients. Zenteek now does the same in software, with 5 filter models to match your preferred sonic character.
  • Bugfix Harmonic Exciter: The effect blend knob added in the last build introduces phase cancellation at 50% that went unnoticed. I rewrote the effect mix and now you can safely and delay-free control the amount of added harmonics.

  • New UI Panel Enhancements: Bass Extender, Harmonic Exciter and the new Vitalizer - all in one place
