FAQ
What permissions are needed and when is it unavailable?

Is any audio recorded or uploaded?
No. Audio is processed and drawn locally in your browser in real time for the waveform, spectrum and volume meter. Nothing is recorded, stored or uploaded, and everything ends when you stop or close the page.
