A portable Windows application for measurement recordings.
Signals, FFT, FRF and measurement annotations — from source data to a graph for your report.
Download for Windows · Quick start · Features · Documentation · Русский
- Consistent response analysis. Compare several responses against a shared reference over the same recording interval. Multiple reference channels can be averaged before estimation.
- A complete measurement workflow. Load a recording → process channels → analyse → add measurement annotations → export a graph for a report.
- A workspace you can move. Take the application, local settings and projects containing source samples to another Windows PC.

| Time signals, zooming and original sample inspection. | Frequency content and channel spectrum comparisons. | Response transfer functions and a separate shared-reference spectrum. |
Click an image to open it at full size. In the FRF example, Reference A / Reference B are averaged before H1/Welch; Response A / Response B have separate curves calculated over the same recording interval.
The scenes show a local working build's native interface with a synthetic recording. Gallery and explanations · Image provenance.
Place points on samples, measure coordinates and intervals, mark events and add vertical or horizontal guide lines. Annotations are saved in projects and included in PNG export.
- Digital filters, individual multipliers and a global channel formula.
- FFT/FRF interval selection, channel names, colours and visibility.
- Curve symbols for grayscale, light/dark themes and configurable shortcuts.
- Large recordings: automatic RAM or disk-backed operation, with calculations using source samples.

Example GUI measurements for v0.17.3: a real 1.024 GB recording, 6,832,000 samples × 8 channels, Auto with data resident in RAM.
| Operation | Time |
|---|---|
| Open the recording | 33.22 s |
| Full raw FFT, one channel | 2.63 s |
| First H1, seven responses | 1.82 s |
| Repeat H1 with reused input preparation | 0.97 s |
Medians of three processes: Windows 10, Ryzen 5 5600X, 32 GiB RAM; OS cache was not cleared. H1: one reference, L=2048, Hann, 50% overlap, mean removal. Results describe that version; time depends on input, processing and resources. Disk-backed work can be substantially slower. Method and memory costs →
- Download the GUI EXE from the latest release and run it from a writable folder.
- Open a LabVIEW
.lvm, tabular.txt/.csv, or the demonstration recording. - Analyse your data, save an
.AMSigproject to resume work, and export a PNG for your report.
No installer, LabVIEW or Qt is required. To move your workspace, copy the EXE, its adjacent AMS.ini and your projects. Starting with v0.17.8-cpu.2, projects save FRF roles, method and L; older projects need CSV or experiment notes. Quick start · Moving your workspace.
GitHub's Source code archives contain sources; the CLI can be built separately.
