Douk Audio Lab TX7 Desktop Display with VU Meter, Spectrum Visualizer and Clock Review
A desktop VU meter and audio spectrum visualizer with seven meter styles, two spectrum modes and four clock faces, driven by AUX line-in or mic pickup on a 960x320 touchscreen.

Our verdict
The TX7 is a $99.99 desktop piece for people who like watching their music as much as hearing it: seven VU meter styles with tunable motion, two spectrum visualizer modes down to 32/64-band detail, and a clock with four faces plus standby scenes on a 960x320 touchscreen. Feed it from a 3.5mm line out or let the mic pick up the room. It is purely a display - the audio path is untouched - and the box includes cables but no USB charger. As desk decor or a gift for a music lover, it is an easy pick.
- Best for
- Desk setup fans and music lovers who want a retro VU meter, spectrum visualizer and clock in one aluminum display.
- Skip if
- You expect it to change how your system sounds, need a US-precision calibrated meter, or want a power adapter in the box.
The Douk Audio Lab TX7 is a desktop display priced at $99.99 that turns audio into visuals: VU meters, a spectrum analyzer and a clock on a 960x320 touchscreen. It is an accessory rather than an audio component - it listens to your signal and renders it, without stepping into the audio path itself.
Seven VU meter styles recreate the sweep of analog needles with a lifelike feel, and motion can be fine-tuned with gain, damping and stiffness controls. The two audio spectrum visualizer modes reveal frequency movement with 32/64-band detail, response curves, real or smooth response, colors and peak/fall timing, so you can match the display to your source and taste.
For quiet moments, the TX7 becomes a desk clock with four clock styles, 12/24-hour formats, two animated scenes and twelve static standby screens. It responds to touch: swipe between display styles, tap into settings and adjust key visuals with on-screen sliders. Audio can come in two ways - 3.5mm AUX line input for direct signal response, or the built-in MIC pickup when you would rather not wire anything. The sandblasted anodized aluminum body measures 124 x 23 x 54mm and weighs 348g, and the box includes a leather storage case, a 3.5mm 1-to-2 cable, a USB-C cable and a 3.5mm AUX cable. Power comes from USB-C at 5V/1A.

What we liked
- Seven VU meter styles with adjustable gain, damping and stiffness for lifelike needle motion
- Two spectrum visualizer modes offer 32/64-band detail, response curves, colors and peak/fall timing
- Choose AUX line input for direct signal response or built-in mic pickup for convenience without wiring
- Clock with 4 styles plus animated and static standby screens keeps it useful when no music is playing
- Responsive touchscreen control with on-screen sliders, bundled leather storage case and cables
Worth noting
- It is a visual display - it watches your signal but does not process or improve the audio path
- Mic pickup mode reacts to ambient room sound rather than the exact line signal, so needle movement is less precise
- The box lists a USB-C cable but no power adapter, so you will likely need your own USB charger
