While capturing some test data to validate the impedance measurement feature, I noticed that the three devices I currently test with weren’t performing equally. As a result, I decided to create a user story to illustrate the differences between my testing devices.

Here’s a quick summary — Don’t buy an iMic for use with FuzzMeasure. If you’re looking for a low-cost device to use with FuzzMeasure for both acoustical and electrical measurements, go pick up an M-Audio MobilePre USB.

Of course, for those of you with built-in audio (PowerBook/PowerMac/iMac users), you’ll only need a preamp and microphone for your acoustical measurements. The built-in audio (although not shown in the article), performs quite well. Apple appears to not have skimped on that aspect of their hardware at all.
