Oscilloscopes and signal generators are handy tools in our labs. Unfortunately, they are not cheap. What if you had such devices already and did not know?
All newer PCs have loudspeakers and a microphone. So they can create sound as well as record it. And usually in decent quality. Like oscilloscopes and signal generators! We only need a connection and software to create the desired waveforms and visualize the measured voltages. Fortunately, such software is available. And the best: We can use it free of charge!
