When using the soundcard as an oscilloscope, the low input impedance is a large disadvantage. Not only would it influence the measured circuit and possibly shortcircuit low input signals. It also would not allow the usage of commercial oscilloscope probes which normally are designed to work with oscilloscope inputs with a typical impedance of 1 Mohm.

I just discovered an app for mac that uses the Audio Input of the computer and the AD-converter in the sound card as an Oscilloscope. First, I was thinking this can't work... but theoretically, it's a great idea! I know it can only measure for frequencies starting from ~20 kHz, but if you need to measure MHz, then it's just fine.

The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The low frequency end is limited by the AC coupling of the line-in signal.
