Music you own.
The engine it deserves.

Bit-Perfect Signal Path
End-to-End
Your files reach the DAC hardware untouched. No resampling, no mixing, no system interference. Zenteek matches your DAC to the source - not the other way around
Equalizer, Zero Resampling
10-band parametric equalizer, baked right in the signal path and operating at native sample rate, featuring emulation of classic PreAmps. With AutoEQ Import.
Analog Soul for Digital Files
Dial in the warmth and glue of classic tape machines. From subtle harmonic richness to saturated character - all processed at native sample rates for zero quality loss.
Stereo under Full Control
Widen or tighten the soundstage, correct Phase Alignment, and Mid/Side Processing. Built-In LUFS Analyzer and Normalizer with adjustable target.
A player should augment, never overwrite. For collectors who care about ownership.
Respecting Your Files.
No surprises.
Your library stays exactly as it is. No renaming. No restructuring. Just lightning-fast access to 100,000+ tracks, indexed for stability. Any destructive operations, like tag writing, are strictly opt-in.
Local discovery.
Build from your history.
With Zenteek, you can discover your library in new ways. No algorithms, no guessing, just private statistics and math. The more you listen, the more Zenteek understands your library and surfaces tracks that you might have forgotten you own.
Deep Insights.
Total Privacy.
Play counts, skip rates, listening trends by daytime - all tracked locally, never sent anywhere. Quickly learn about your current listening habits and discover which tracks are quietly becoming your new favorites.
Playlists tend to become collections.
Mixtapes are decisions.
Curate with Intent.
The Art of the Mixtape.
The tape format from the past, with its limited time budget, is a great inspiration for playlist creation. Choose 60 or 90 minute lenght, search and quickly add tracks to either side. All in one intuitive interface.
A digital Tape-Rack.
All in one place.
Once curated you can store mixtapes on a virtual tape rack. You can drag and drop them in any order you like, color and label them and play them with one click. Enjoy the perfect mix at the right time. Pair with the built-in tape saturation for that analog touch.
Bit-Perfect Radio.
Enjoy Hi-Res Stations.
Zenteek applies the same uncompromising audio pipeline to all web radio streams. Experience bit-perfect output in exclusive mode, native sample rate EQ, and DSP.
Take your music everywhere.

FAQ
macOS routes audio through a shared system mixer, which may resample and apply system processing. Zenteek bypasses this entirely.
In Exclusive Mode, your audio hardware is accessed directly:- Native sample rate per track
- No system mixer
- No sample rate conversion
- No system-level processing
The DAC is configured to match the source file during playback.
No, unless explicitly enabled. Tag editing and enrichment are opt-in. When saving changes, you can choose whether to write to the source file or keep edits in Zenteek’s local database.
Deletions use soft-delete and can be restored. Files remain unchanged unless you choose to apply edits.
DSF (DSD64–DSD256) is converted to high-resolution PCM before playback. This allows playback on standard DACs without native DSD support.
Example with a 768 kHz DAC:- DSD64 → 352,8 kHz
- DSD128 → 705,6 kHz
- DSD256 → 1.411,2 kHz → clamped to DSD128 (705,6 kHz)
- DSD512 → 2.822,4 kHz → clamped to DSD128 (705,6 kHz)
Native DoP output is planned.
Most EQ tools on macOS break bit-perfect playback because they rely on the system mixer. Zenteek doesn’t.
The EQ runs inside the playback engine:- Processes at the source sample rate
- 32-bit float precision
- No sample rate conversion
Zenteek is offline-first.
All network features - radio, artwork, enrichment - are opt-in.
When enabled, internet connections are limited to “zenteek.app” for core services (enrichment, license validation, updates, crash reporting). Connections to third-party services only occur when explicitly used (e.g. scrobbling or streaming), and are made directly.
All infrastructure is hosted in the EU and subject to EU privacy laws.
