You can measure AC voltages which are within the input voltage range of the interface. The interface doesn't care if its a 1kHz test signal or Taylor Swift.I‘m sorry but how can you measure electrical signals, volts, amps, etc. with an audio interface like Focusrite, Motu, etc.?
For amps, DC volts etc, a good multi-meter is the best option.
