loudspeaker Audio and Multimedia Tools

This program generates signals to test loudspeakers with the help of a synchronised LED stroboscope. The only external hardware needed is a two channel amplifier and an LED flashlight. Traditionally these tests are done with dedicated hardware devices costing several thousand dollars or Euros. Here the computer sound card supplies the two signals to the two channel amplifier.
