V1.2.3 Is Live And It Is All About Shaping Your Sound
· by Kjell
This update is about one thing: sound. While previous releases focused on playback fidelity and discovery features, 1.2.3 turns its attention to how music actually feels when it hits your ears. Three new tools give you meaningful control over the psychoacoustic character of your listening experience. And they all live together in one place.
Psychoacoustics, meet your new home
The centerpiece of this release is a dedicated UI panel that brings the Bass Extender, Harmonic Exciter, and the brand-new Vitalizer together under one roof. Having these tools side by side isn't just convenient it changes how you use them. You start hearing them as a system.
The Vitalizer is the new arrival, and it's the one worth getting excited about. Inspired by the SPL Vitalizer, it works through three subtle layers: resonant bass contouring that adds body without muddiness, gentle mid-range demasking to bring instruments out of the mix, and a high-frequency "air" lift that opens up the top end. The result is a wider, more three-dimensional sound, the kind that makes you feel like you're hearing your library properly for the first time.
The Harmonic Exciter picks up a dry/wet knob in its new home, meaning you can finally dial in exactly how much harmonic color you want added. This used to be a one-trick pony, but now you can blend it to taste and gradually add harmonics.
Reconstruction filters
High-end DACs have long used reconstruction filters to handle the ultrasonic ringing that digital-to-analog conversion introduces around transients. Zenteek now does this in software, with 5 unique filter models to choose from.
Depending on the recording, some listeners will prefer a sharper, more clinical transient shape; others will reach for something warmer that rolls off more gently.
To be clear, while technically doing the same, It does not replace functionality of expensive DACs. It conditions the signal at the source, reducing pre-ringing before it reaches your DAC. The effect is most noticeable with onboard or portable DACs, but audible on any setup with transient-rich material.
UI and Maintenance
Volume and mute controls have been repositioned to make room for the new panel. It'll feel slightly different at first, and yes, I'll need to update some screenshots. That said, in testing I adapted to it faster than expected. Once your volume is normalized across all tracks using the built-in LUFS analyzer, you reach for that knob a lot less than you think. Give it a week.
The spectrum analyzer bands have been rebalanced for a more even spread across the Y axis, and the dB labels are back. They were originally hidden to keep the embedded display from feeling cramped, but the spectrum analyzer is fundamentally an analytical tool, and analytical tools should show their numbers. If the in-player view feels too busy, open it the way it was meant to be seen: Shift+Cmd+M for the Mini Player, right-click to show the visualizer, then scale the window up. Suddenly there's room for everything.
The effect panels have been reorganized and picked up new icons: Enhancements and Output Tools now group their settings more logically, and the whole interface feels more like a single coherent thing as a result.
The Harmonic Exciter's blend knob, introduced in the previous build, was quietly causing phase cancellation at 50%. The effect mix has been rewritten from scratch. It's now delay-free and safe across the full range.
