Sonaurelis In development

Beacon · Signal Monitor · Free

Watches everything. Touches nothing.

Beacon sits on your bus, bit-transparent and zero-latency, and watches your signal for the faults you would otherwise find too late — clipping, DC, hum, dropouts, runaway resonance, feedback risk. Free, for everyone.

Beacon Signal Monitor — full interface, reference render

Reference render — Beacon session, Sonaurelis Visual Standard v2.2

  • Bit-transparent and zero-latency — the audio path is never touched
  • Six detector families: level, resonance, feedback, dynamics, stereo, technical
  • Evidence, not vibes — alerts carry measurements and stated confidence
  • Free for everyone — no account, no email, nothing to unlock

The signal field

An event, with evidence

The field draws your spectrum with persistence and history — and when something develops, Beacon names it in plain language: Persistent concentration near 3.2 kHz — 6.1 dB above the recent surrounding spectrum for 8.4 seconds · developing. A measurement, a duration, a status. Never a vague warning light.

Beacon will not cry wolf: red is reserved for verified critical technical faults. Everything contextual or inferred tops out at Attention, and inferences state their confidence.

Live view

For the moment you can’t stop

On stage or in a take, you don’t read spectra — you glance. Live view answers in glances: headroom, channel health, feedback watch, and the last mark you dropped, each as a card you can read from across the room. Mark a moment with one press and deal with it when the music stops.

Feel-first macros

Tune the judgment, not the sound

Beacon has no sound of its own to shape. Its five macros tune how it judges — how much evidence, how long, how fast, against what baseline, with how much memory.

Beacon's macro band: Confidence, Persistence, Response, Baseline, History — reference render
  • LenientStrict

    Confidence

    How much evidence an event needs before you hear about it.

  • MomentarySustained

    Persistence

    How long something must last before it matters.

  • SteadyFast

    Response

    How quickly the field follows the signal.

  • FixedAdaptive

    Baseline

    What “normal” is measured against.

  • ShortLong

    History

    How much of the past the timeline keeps.

The watchlist

Six families, all visible

The drawer holds the watchlist: level, resonance, feedback, dynamics, stereo, and technical — each with its own sensitivity and minimum duration, all six visible at once even at the smallest window size.

Pin a frequency you are hunting. Ignore the mains hum you already know about. Keep history across the session, and export what Beacon saw.

Truthful by construction

Health, honestly

The rail keeps sensitivity at the top, over calibrated input and true-peak meters with a held TP max, a health module that summarizes the watch — CALM…ACTIVE, with developing and critical counts — and a loudness & stereo module: LUFS, crest, correlation, mono compatibility.

The suite rule applies with extra force to a monitor: every moving pixel traces to real measurement of your signal. A monitor that decorated would be lying about the one thing it exists to tell.
