Getting Started

To start measuring your audio hardware or listening environment, you need:

  • A computer with a soundcard
  • A measuring microphone
  • Kuray

Measuring Frequency Response

The first thing you might want to try is measure the frequency response of a loudspeaker. Actually, unless you happen to have acces to an anechoic chamber, you’ll be measuring the combination of your speaker and your room (and your microphone).

To do this with Kuray you need to plug in a microphone into your soundcards input. Beware to set up your sound settings not to output the signal of your microphone directly to the speakers to avoid feedback. Start Kuray and hit Measure. It will generate and play a sine sweep, record it via the microphone and then calculate the frequency response from that. You should get a plot like this:
