[QUOTE="Vaughan, post: 32933, member: 693"] Frequency response on mic-in is limited, which is why you need to use line in. A local loopback is required from line out to line in to provide a reference signal for the measurements, and mic inputs have high noise levels and often have very restricted low frequency extension. A USB sound card would be required if you only have a mic-in. The more expensive mics have better accuracy at higher frequencies. How high do you want to measure ? At 40 kHz + ? :D Regards, [/QUOTE]
