AudioTester

With the help of a high quality soundcard 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.

Sound and tones to wave files
· Asyncrone Impulsmeasurement
· Measurement of Distortions vs. Power
· Measurement of Thiele Small Parameter
