The range line under the tabs states whether results use the selection or the whole session. Shift-drag on the timeline to select.
Range statistics#
Make the streams you want visible as timeline tracks and optionally select a range.
Click Compute for visible tracks.
Each stream lists, per channel: count, and for continuous signals min, max, mean, median, SD, RMS and Δ (end − start); spectral peaks for audio; value counts for events and categorical data; and notes.
Correlation#
Pick stream A and its channel, and stream B and its channel (numeric streams and event streams are both available).
Set max lag (s) (default 2) and click Compute.
Read the results: the common grid step and paired sample count, Pearson r, Spearman ρ, the lag estimate and its r (positive = B follows A), the combined timing uncertainty of both streams, and any warnings. The plot shows cross-correlation against lag.
Correlation describes temporal association only.
Impulse response#
Averages a signal around repeated onsets with a 95 % confidence interval.
Onsets — an event stream; Kind — optional event-kind filter.
Signal and Channel — the numeric stream to average.
Pre / post (s) — window around each onset (default 0.5 / 1.0).
Click Align, average and compute 95% CI. The plot shows the mean (line) and CI (band) with the onset marked; the header lists trials, step and method.
Detectors#
Each detector lists its description, its default parameters and a Run button. Unavailable detectors state which recorded data they need. Detected events become a detected.<detector> stream with a DERIVED badge, appear in the Events panel and timeline, and feed Resonance, Shockwave and the Lens.
| Detector | Finds | Defaults |
|---|---|---|
| Audio impulse | Envelope above the median noise floor, refined to the first raw sample ≥ 50 % of the local peak. | window 5 ms, k 10, floor 0.02 FS, refractory 0.25 s |
| Accelerometer transient | Deviation of the acceleration vector from a running-median baseline (MAD threshold). | baseline 0.5 s, k 8, floor 0.5, refractory 0.2 s |
| Signal-strength transition | Step change in mean RSSI between adjacent windows. | window 0.5 s, min step 6 dB, refractory 1 s |
| Device appearance | First sighting of each BLE advertiser. | — |
| Backlight change | Change of the OS backlight setting between polls. | min step 0.01 |
| Stimulus onset (host markers) | Trial host markers and haptic commands of non-sham trials. | — |
| Video motion onset | Motion energy (mean |ΔY|) above median + k·MAD. | k 8, floor 1.0, refractory 0.5 s |
| Packet burst | Requires packet/traffic counters. | — |
| RF peak appearance / disappearance | Spectral peaks that appear or vanish between sweeps. | threshold 12 dB, max gap 1 sweep |
| RF band power transition | Step changes in RF band series. | samples 3, min step 6 dB, refractory 1 s |
Compute video motion energy builds the motion-energy stream on demand for long videos (it is computed automatically for shorter ones).
