1.2.0 Release - New Engine, Tahoe Ready And Improved Crossfeed
· by Kjell
A More Robust Playback Engine
The most significant change in 1.2.0 happens entirely under the hood. The audio pipeline has been redesigned from the ground up - device negotiation, format handling, and the transition between tracks and sample rates are now managed through a dedicated Engine layer with a clean separation of responsibilities. In practice this means: unplugging your DAC mid-playback, switching between shared and exclusive mode, or moving between 44.1 and 96 kHz material no longer causes the occasional freeze, silent dropout, or phantom state that some of you reported.
The new architecture serializes all device and format decisions through a single control path, eliminating the race conditions that made those bugs so hard to reproduce, which is why it took a while for me to identify the root cause. If you've ever had to restart Zenteek after a redbook-to-hires upgrade or a device switch - that should now be a thing of the past.
Improved Crossfeed - Closer to the Meier/Bauer Design
The Crossfeed filter has been updated with a low-frequency shelf compensation, bringing it closer to the original Meier and Bauer circuit designs that the audiophile community has long considered the reference for headphone crossfeed. The previous implementation handled the high-frequency crosstalk well but left the low end slightly uncompensated - the new unit corrects that, resulting in a more natural stereo image and less listening fatigue on long sessions.
If you're using Zenteek with an open-back headphone and a quality DAC, this is worth revisiting with your usual reference material. I can't get enough of this effect.
New Settings Window
Settings have moved to a dedicated window with a sidebar navigation, replacing the single-panel layout that was getting crowded. Playback, Audio Output, Metadata, Integrations, Appearance, and Privacy now each have their own section - easier to navigate and with room to grow as new features land as i am far from done with Zenteek :)
macOS Tahoe Ready
The option pickers throughout the interface have been replaced with a custom control that renders and behaves correctly on macOS Tahoe's updated window chrome. A small fix, but the kind of thing that matters when you care about the details. Sorry if you were wondering why it didn't look like on the screenshots with macOS 26. Zenteek UI was originally built on macOS 15 and i had some audio related issues (like so many others) with Tahoe that kept me from updating. Enjoy!
