Doppler with free fall bluetooth speaker?
Thanks solid! Very nice, and that setup is simple enough.

Actually, just 3 Hz phone shaking in front of a 440 Hz youtube video shows doppler 440±2 Hz, but also strange flat one second long slopes every second second between otherwise nicely sine shaped curves (in groups of three, i.e. also every second second).

Seen those (see png)?

What makes them?

Best regards.
