The page lists WAV, AIFF, MP3, and M4A input and says analysis and rendering use Web Audio, Canvas 2D, and MediaRecorder in the browser, without an upload server or external libraries. Its free tier is limited to 15-second clips and does not export the meter; the $10 one-time PRO tier adds 30- and 60-second clips, custom colors, and measurement displays. The creator reports 82 passing measurement-related unit tests and ±0.1 LU accuracy against EBU Tech 3341 test signals.
