Strobe Sync Pulse Generator
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, inflexible hardware devices costing several thousand dollars... The other signal is the light trigger pulse on the right channel. ... The speaker signal (sine wave on the left channel) is amplified and sent to the loudspeaker under test. ... In this program the computer sound card supplies the two signals to the two channel amplifier.
