With this software and a simple external hardware, the sound card input of a PC can be used to measure stationary or slowly changing analog signals (e.g. voltages). The hardware converts the input signal into a voltage proportional frequency. The software measures the frequency via the sound card and calculates the corresponding input signal level which is displayed numerically and in a “scope-like” view.
