~ Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics). ~ Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card). ~ Sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise. Typical Applications include test tone generation in studios for the alignment of levels, calibration and testing of audio equipment or speakers, tuning music instruments as an accurate reference tone, demonstration of audio principles to students and more. and Europe as well as wire transfer money to local bank accounts in your country.NCH Sound Tone Generator lets you create audio tones, sweeps or noise waveforms using a Windows computer with a sound card or a PocketPC handheld.

The two channel amplifier can be a normal audio hifi amplifier. This is how the loudspeaker is connected for the test: Note that these effects are not just visible with cameras, but with the normal human eye.
When switched on, the loudspeaker or vibrating object can be watched in slow motion like in these videos ( link). I use a standard LED flashlight (British English: torch) connected to the loudspeaker output of a normal audio amplifier as a stroboscope. It is sent to the external trigger input of a stroboscope or it can also be amplified and sent directly to LEDs.
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. The computer sound card supplies the two signals to the two channel amplifier. The only external hardware needed is a two channel amplifier and an LED flashlight.Ī typical hardware configuration looks like this : Traditionally these tests are done with dedicated hardware devices costing several thousand dollars or Euros. This program generates signals to watch loudspeaker movement (or any other periodically vibrating device) with the help of a synchronised stroboscope.
