Happy Pi Day! Today (3.14) is "National Pi Day"!
Pi is a pretty important number in the audio world. It is used in calculations involving frequency as related to filters and wavelengths.
Someday down the road I am hoping to design/build a phono preamp. Pi will need to be part of the complex calculations for the RIAA filter time constants.
But first I have to learn some new CAD software for circuit design and PCB layout.
In the mean time, please enjoy this beautiful song about Pi.
