Questions about signal quality tools
How many open-source signal quality tools are listed?
19, counting tools with this as their main or secondary category. By signal: PPG 14, ECG 8, IMU 1, EEG 1, EDA 4 and Respiration 2, multi-signal 2.
Which programming languages do these signal quality tools use?
Python (14) and MATLAB (3); 2 do not state a language. A tool that names more than one language is counted under each.
Can I use these signal quality tools in a commercial product?
It depends on each licence. Of the 19 tools, 16 list commercial use as yes, 1 as no and 2 do not state it. Each tool page shows the licence exactly as the project publishes it; read the licence in the project repository before you build on it.
Listings, summaries, licences and commercial-use fields are shown as recorded for each project, as of Oct 21, 2026. Maintenance is computed from the date of the last commit. Check the licence in each project’s repository before you use it.
