Live PWA tool
Open the SOUNDTEST.PRO evidence recorder.
The live app keeps microphone analysis local in your browser and supports dBA/dBC/dBZ, LAeq, L5/L10/L50/L90/L95, GPS notes, photos, audio/video, CSV, PDF, and evidence manifests.
Recommended test flow
- Open from HTTPS, localhost, or 127.0.0.1.
- Start monitoring and allow microphone access.
- Capture an evidence photo and one short audio or video record.
- Export PDF/CSV and save media from the Records page.
