Your room is the biggest error in your system—it can swing the response at your listening seat by ±10 dB or more. Unsampled measures it with an app, then corrects it with analog filters. Your music never becomes a sample.

Illustrative simulation, not a production measurement. Peaks are corrected; the null near 50 Hz remains. EQ cannot fix nulls—and we do not claim to.
The biggest error in your analog system is not in your system at all.
Below 300 Hz, a typical listening room imposes peaks of +6–10 dB and nulls deeper still—a larger error than the differences you have spent years voicing your system to achieve.
Analog room EQ is not new. The Rives PARC proved it two decades ago, and mastering-grade analog parametrics have always existed—if you were willing to tune them by ear, with no measurement and no recall. But nothing measures your room and sets itself. Every automated correction system on the market digitizes your signal to do it: analog in, converter, DSP, converter, analog out.
If you have spent years keeping converters out of your vinyl path, that was never a trade you were willing to make. Automated correction with the path left analog—that is the gap Unsampled closes.
The intelligence lives beside the signal path, never inside it. Measure, compute, set the filters—then disconnect the computer and listen.
Place the individually calibrated USB measurement microphone at your listening seat, then at a few positions around it. The app sweeps your speakers and corrects what is common to all of them—not the quirks of one point in space. The microphone’s unique calibration file is applied automatically.
The app identifies the room’s dominant modal peaks below ~300 Hz and computes a parametric correction curve. Correction is cut-focused: the system will not boost into nulls, waste amplifier headroom, or punish your woofers.
The curve is written to Unsampled’s digitally controlled, fully analog parametric EQ. Planned architecture: relay-switched precision filter networks; no VCAs or digital potentiometers in the audio path. The control signals are digital. The audio path never is.
One high-frequency band is reserved for you: a broad, gentle analog shelf for character—a touch more air, a brighter presentation, or a softer top for a lively room. Set it by ear, save it, and recall it by name. The bass is science. The top end is yours.
The app connects to Unsampled for digital control only, over isolated USB. It never touches the audio. Measurement sweeps play through your system only during setup; nothing from the measurement chain remains in the listening path.
Unsampled exists for a very specific listener. That means being as clear about its limits as we are about its purpose.
We built Unsampled for the listener who wants the room fixed and the signal path left alone.
There is no universally right tool. There is only the right compromise for your system, your room, and your priorities.
Yes, we put the rows we lose in the comparison. Both alternatives are excellent at what they do. If digitizing your signal does not bother you, buy the DSP box—sincerely. Unsampled exists for when it does.

There is no factory and no finished chassis behind this page—deliberately. Unsampled is in development, and we are validating demand before we build. Your reservation is how we know. If you would rather watch first, the build log below is free.

The deposit is fully refundable any time before your unit ships and is applied to your final balance. Reservation holders receive the lowest first-run price offered to anyone.
The first run needs 100 reservations. We make the build/no-build decision by December 31, 2026. If we fall short or cancel the run for any reason, every deposit is refunded in full.

No. The audio path is 100% analog from input to output. Only the measurement—a separate microphone—and the control signals are digital, and neither is in the path the music travels.
Because it will be verifiable, not just printed. Before anyone pays a balance, we publish the full audio-path schematic. Every production unit can be tested by its owner: pass a high-frequency tone through it—no brickwall filter; FFT the noise floor—no quantization floor or sample-clock spurs; latency indistinguishable from a wire. Third-party measurements and teardowns are welcome.
The fair question—you have spent years keeping boxes out of your chain. Full measurements, including THD+N, noise floor, and bypass-versus-engaged delta, will be published before any balance is charged. The unit has a true hardware bypass relay: bypassed means a wire, even when powered off.
Planned: settings latch into the analog section and the control clocks gate off after configuration; the USB interface is galvanically isolated; and the unit operates fully standalone with the computer disconnected. The measurement white paper will include noise-floor FFTs with USB connected, disconnected, and mid-adjustment.
Modal bass peaks—the errors your room adds that you hear most—plus a high-frequency character shelf you set by ear. Four parametric bands per channel: all but one perform cut-focused correction below ~300 Hz, never boosting into nulls, and one is a broad high-frequency shelf for your own voicing. It does not fix phase, timing, or deep narrow nulls; that requires DSP, and using DSP would defeat the point.
Yes. The computed curve is a starting point, not a black box: every band is fully editable, target curves are selectable—flat, tilted, or house curve—and import of your own REW measurements is planned. Correction and character save together as named presets for recall from your listening chair.
Above the room’s transition frequency, an in-room measurement mixes your speakers’ direct sound with reflections. “Correcting” a good speaker from that curve makes it worse, so we refuse to do it. A broad, gentle high-frequency shelf is a taste decision, not a measurement problem. That band belongs to you.
At line level, between your preamp—or phono stage output—and your power amplifier. Planned I/O includes balanced XLR and unbalanced RCA. An integrated amplifier with a tape loop or processor loop works too.
An individually calibrated USB measurement microphone, UMIK-class, whose unique calibration file is applied automatically. Phone-microphone measurement with per-device calibration is on the roadmap, but we will not ship a measurement we cannot stand behind.
