TFD Scope is a useful utility that realizes observing of signals simultaneously in time and frequency domains (TFD). It uses your sound card. You can connect a microphone or other signal sources to your sound card and observe a signal waveform as well as spectrum in real time.

The program provides two channel signals analyzing with refreshing rate of time and frequency windows - 10 frame/s. The features of the program are printing signal and frequency distribution curves, data saving in usual ASCII-text files and fast embedding to Excel worksheet with creating charts.
