Measuring your system

1. 1Click Calibrate in the sidebar.
2. 2On the setup page, choose Manual Measurement (Open →).

You'll see Real-Time Measurement, with the note "Play pink noise and capture the room response." If the app isn't set up yet, it shows Device Setup Required first — pick your mic and output, then Apply (Chapter 12 — Settings).

Click to zoom

1. 1Click Start Noise. The app plays pink noise through your selected output and shows the live response. The status pill reads OK — Measuring — playing pink noise.
2. 2Watch the frequency-response chart fill in.
3. 3Click Stop Noise when you're done.

Auto Capture — one-click measurement

If you just want a clean capture without watching the chart, click Auto Capture (wand). It does the whole run for you: starts the noise, waits until the measurement is stable, takes a snapshot, then stops the noise. While it waits, the status pill reads Auto Capture — Waiting for a stable measurement with a progress percentage. To cancel, click Stop Noise — no snapshot is taken.

Reading the charts

• Frequency response (top) — level (dB) against frequency (about 25 Hz to 20 kHz, on a log scale). This is the shape of your sound: peaks are too-loud regions, dips are too-quiet ones.
• Coherence overlay — a coloured trace (red → yellow → green) showing how trustworthy the measurement is at each frequency. Green means reliable; red means noise, reflections or timing problems are making that part of the measurement unreliable.
• Phase response (bottom) — the timing/phase of the signal, wrapped between +180° and −180°. Where the measurement is too unreliable to give a meaningful phase reading, the line is simply left blank rather than drawn as noise.

Hover the chart for a readout of Freq, Gain, Phase and Confidence (the coherence at that point, as a percentage).

Live diagnostics below the charts

While you measure, a collapsible Diagnostics panel appears below the charts. It runs the same room analysis as the results page, but live: plain-language cards pointing out reflections, room nulls, resonances and measurement-quality problems as the microphone hears them. Move a speaker or quieten the room and watch the cards update.

• Hover a card to shade its frequency band on the chart, so you can see exactly where the finding lives.
• Select a snapshot and the panel describes that capture instead of the live signal (the panel's title shows the snapshot's name).
• The charts and snapshot list stay pinned at the top while the diagnostics scroll beneath them.

For what each card means and what to do about it, see Chapter 15 — Diagnostics.

A snapshot freezes the current measurement so you can keep it, name it, and compare it against others (for example, left vs. right, or before vs. after moving a speaker).

Capture a snapshot

1. 1While measuring, click Take Snapshot (camera). (It's greyed out until you start measuring.)
2. 2The Edit Snapshot Details window opens straight away. Give it a Name, pick a colour, and optionally set the Speaker ID (which output it belongs to). Click Update.

Or let the app do it: Auto Capture (see above) starts the noise, waits for a stable measurement, and takes the snapshot for you.

The Realtime row at the top of the snapshot list is always the live signal. Each captured snapshot below it has:

• a colour dot — click to show/hide it on the chart;
• a name — click to select it (click again to deselect);
• a red ✕ — delete it.

Work with the selected snapshot

The Selected Snapshot bar shows the current one, with:

• Edit — rename / recolour / reassign it.
• Manual offset controls (see below).
• Reference — set a snapshot as the reference (Set as Reference) to compare others against it; Remove clears it.

Manual offsets (Delay / Gain / Polarity)

You can nudge a snapshot's timing, level and polarity to see how it would line up — without touching the device:

• Delay — + / − step by 0.5 ms (hold Shift for a fine 0.025× step); the ↩︎ button resets to 0.
• Gain — + / − step by 0.5 dB (Shift for fine); ↩︎ resets.
• Polarity — a single button that flips polarity (amber when inverted).

These update the chart instantly. They're a measurement aid, not a device change.

Combine, export and load

The row of buttons under the snapshots:

• Combine — sum two or more snapshots into one response (Combine Snapshots; pick at least two).
• Create Calibration — start room correction (or Align Only) from your snapshots — see Chapter 9 — Room correction & calibration.
• Export CSV / Export All — with a snapshot selected the button is Export CSV (that one snapshot); with nothing selected it's Export All (one CSV per snapshot into a folder you choose). The CSV carries the snapshot's name, colour, sample rate, latency and offsets — see Appendix B — File formats.
• Load — import one or more snapshot CSVs back in (multi-select).

Click the gear (Measurement settings) in the toolbar to open the settings panel.

The panel also holds the Latency Drift Check diagnostic — see Chapter 15 — Diagnostics.

Averaging modes

Averaging controls how the live curve settles. (Stop the noise first — the dropdown is locked while a measurement runs.)

• Slow / Fast / Ultra-Fast behave like a level meter: the curve continuously eases towards the latest sound, settling over roughly 1.5 s / 500 ms / 250 ms. Slow is the steadiest and the most trustworthy.
• FIFO4 – FIFO32 average exactly the last 4–32 frames of data. The trace settles in a fixed, predictable time and then stops changing if the room does — good for careful before/after comparisons.

Custom graph view

Pick Custom… under Graph Scale to set your own window: the Custom Graph View dialog asks for a Scale (the ±dB window), and a From / To frequency range in Hz. Click Save to apply. While Custom is active, an Edit button appears next to the dropdown to reopen the dialog.
