Strobe Sync Pulse Generator

Strobe Sync Pulse Generator generates signals to test loudspeakers (or any other periodically vibrating device) with the help of a synchronised stroboscope.

This program generates synchronised signals that drive the speaker and an LED light stroboscope which enables you to see the speaker movements in adjustable slow motion speed.

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. In this program the computer sound card supplies the two signals to the two channel amplifier.

The speaker signal (sine wave on the left channel) is amplified and sent to the loudspeaker under test. The other signal is the light trigger pulse on the right channel. It is sent to the external trigger input of a stroboscope or it can also be amplified and sent directly to LEDs. A standard LED flashlight (British English: torch) is ideal as a stroboscope.
