Scrolling Spectrograph

by Tom Veatch.

First draft.
(Ask me to improve it.)

After you click and it starts scrolling, start talking. Sing, play instruments, cluck and click and pop. It's cool.

Watch the frequency-energy-time pattern of what you actually say. It's not what you thought you said, it's what you actually said.

The spectrograph doesn't lie.

This is the real data of speech and acoustics.

Click again to Pause (repeat to speed it up across the screen).

This tool is not yet as good as the Kay Sonograph I used in grad school, but it's a start.

Tested working on Chrome under Windows 10; and on Safari on iPhone, iPad and MacBook. Let me know if it doesn't work on your platform.
