With the help of a high quality sound card your PC will be an audio lab. You measure frequency responses of loudspeakers crossovers, distortion of any audio equipment and impulse responses of loudspeaker systems. Specification see here
The audioTester works with all high quality sound cards and Windows. Samplerates up to 768kHz and data witdh til 24bit are possible.
A help file with many measurement examples is included.
