Does anyone have any ideas about the best way to build a device that takes an input from an external microphone, shifts the signal 180 degrees out of phase, and then re-emits it with little loss of resolution of the waveform in the process? It would be great if it could also work from frequencies of about 20Hz up... Maybe there is a mail-order kit for something similar that someone know of? Thanks in advance...
