What topic it changes all the time nobody was talking about tuning forks and beat freq B4 yesterday where you been ?
No telling what the topic(s) will be 2 morrow that's half the fun of it
I like the English copper whistle beat freq thing, fast Fourier transform (FFT) thing is interesting ,clever blokes aren't they?
I wonder if a coaches/teacher /traffic cop whistle does that (beat freq.) w/o the pipes anybody know? what about dog whistles ?
