Advanced local measurement

Electrical loopback test.

Measure a confirmed electrical return path only after the browser has assessed whether it can support each metric honestly.

Electrical loopback v1Local only

Measurement preflight

Confirm the path before the number.

Use a physical electrical output-to-input connection, not a speaker and microphone in a room. WaveLocus will capture the return locally, correlate it with a known chirp and withhold invalid metrics.

  1. Connect an output directly to an input.Use suitable attenuation and keep monitor volume low. Do not route headphone or line output directly to an input that cannot accept it.
  2. Select the returning input.Browser labels become available after permission is granted.
  3. Confirm the path and run the preflight.Each run repeats the same local stimulus to estimate variation.
StatusConnect an electrical output to an input, then request the selected input.
Eligibility decisionMethod v2

No measurement yet

Metrics stay withheld until preflight.

The result panel will not show a latency, level or polarity number until a local preflight produces a corresponding eligibility decision.

Reading the result

Eligibility comes first.

Reliable

The confirmed path, settings, headroom and correlation support this local estimate.

Limited

A result is available, but processing state or signal confidence warrants caution.

Unavailable or invalid

Unsupported channels, unconfirmed paths, clipping or weak correlation withhold the metric.
