I have a Windows Media file of a pulsating sound wave, probably of two octaves, centered around 5 khz. I downloaded two oscilloscope programs, Oscilloscope 2.51 and BIP Lab Oscilloscope 3.0, to see if I could measure the frequency and amplitude of this sound wave, no luck. What I'd like to eventually do is to build on a bread board a circuit, utilizing a 555 timer chip and an audio amplifier chip, etc., to drive a tweeter, to duplicate this sound. Any suggestions? tks.............cariboo1946
