Signal processing.Made graphical.

Create complex signal-processing workflows by connecting blocks, then reuse them across complete test campaigns. SignalDojo keeps the method visible, the results traceable and your engineering data local.

ONE GRAPHICAL ENGINEERING WORKBENCH

From one recording to a complete test campaign.

SignalDojo turns complex processing into an inspectable visual system. Design once, inspect every step and reuse the workflow without rewriting analysis scripts.

SignalDojo — Motor Current Test Campaign

01

Build visually

Drag blocks onto the canvas and connect imports, filters, mathematics, FFTs, statistics, scopes and exports. Parameters stay visible and editable.

02

Automate test campaigns

Run one validated workflow across folders of recordings, publish named metrics and evaluate pass, warning, fail and error results together.

03

Compare and report

Inspect scopes, spectra and tables; compare selected runs against a reference; then export campaign evidence for review.

ENGINEERING CAPABILITIES

Designed for real analysis work.

Move from raw sensor data to repeatable evidence in one responsive desktop environment—without losing sight of how a result was produced.

01

Visual workflow editor

Searchable blocks, drag-and-connect diagrams, editable properties, comments, groups, minimap, undo/redo and automatic layout.

02

Signal conditioning

Low-, high- and band-pass filtering, resampling, alignment, expressions, channel mathematics and data cleaning.

03

Analysis & displays

Scopes, FFT, PSD, STFT, spectrograms, statistics, data tables, persistent result views and measurement tools.

04

Automated campaigns

Folder discovery, batch execution, published metrics, pass/fail requirements, retry, caching, comparisons and reporting.

05

Engineering data formats

Work with CSV, TSV, Excel, JSON, NumPy, HDF5 and TDMS data, then export results in practical formats.

06

Local and extensible

Process sensitive recordings on your own computer and extend the open block registry and plugin API for new workflows.

1
Import

Load recorded engineering data.

2
Connect

Build a visible processing path.

3
Run

Execute once or across a campaign.

4
Decide

Review metrics, limits and evidence.

You may run, study, copy, modify and redistribute SignalDojo. Distribution of covered binaries or modified versions must meet the GPL’s notice, licensing and corresponding-source requirements.

PROJECT MARKS

Fork freely. Brand clearly.

The SignalDojo name, icon and logo identify the official project. Modified distributions can exercise every GPL right while using distinct branding and accurately saying they are “based on SignalDojo.”

OPTIONAL SUPPORT

Help keep engineering software accessible.

SignalDojo is free regardless of whether you contribute. If the project saves you time, an optional donation helps fund testing, documentation, hosting and future development.

QUICK ANSWERS

Practical details.

Is SignalDojo really free?

Yes. Version 1.2.6 is available without a trial, subscription, licence server or mandatory payment. Donations are optional.

What Windows versions are supported?

The official 64-bit installer is intended for Windows 10 and Windows 11. Python and the required runtime dependencies are bundled.

Does SignalDojo upload my recordings?

No cloud service is required for analysis. SignalDojo processes your recordings locally on your computer. You choose what you export or share.

Can I modify and redistribute it?

Yes, under GPL-3.0-or-later. When distributing covered binaries or modified versions, comply with the GPL’s applicable licence, notice and corresponding-source requirements.

Can a modified build still be called SignalDojo?

Software rights and project branding are separate. Unofficial modified distributions should use distinct branding and may accurately describe themselves as “based on SignalDojo.” See the trademark policy for details.

Where should I report a problem?

Open a public issue in the GitHub repository when the report contains no confidential information, or email the project for support and private enquiries.
