MSGEQ7

The MSGEQ7 is an IC designed to analyze sound (actually, any signal of varying voltages; in the case of sound or music, a signal as from a microphone). The chip measures aspects of input in seven frequency bands, and can provide output related to one (at a time) of these bands as an analog DC voltage signal.
