[PD] midi to freq equation

[CK]

I read:
> someone please give me the equation for miditofreq, please?

from x_acoustics.c:

> float mtof(float f)
> {
>     if (f <= -1500) return(0);
>     else if (f > 1499) return(mtof(1499));
>     else return (8.17579891564 * exp(.0577622650 * f));
> }

regards,

x
