This Test Tone Generator (TTG) turns your PC into a scientific, professional function generator and enables you to

  • Test and tune loudspeakers, audio devices or complete sound systems
  • Teach others about sounds and frequencies
  • Create sound effects

It can generate a multitude of wave forms at any frequency your sound card can produce. Output is possible up to 24bit and 384kHz sampling rate and only limited by the capability of your sound hardware. Internally the signal is generated and processed in 64 bit floating point accuracy.

The use of the software is not limited to audio applications. Some of our customers...

  • use the software to check and mask tinnitus.
  • have built mosquito repellent devices.
  • are some of the biggest technology or media companies in the world. The computer you are using to read this is likely to contain components from some of our customers

It's unique frequency slider allows you to change the frequency in real time - just like an analogue function generator.
Signals created can be saved as a .WAV file in order to make a test tone CD.
You can run scripts of test tones and save memory pre-sets of fixed or sweep test signals to disk.
If you have multiple sound cards in your PC you can manually select the one you want to use for each instance of the program.


Selectable crest factors for pink noise and white noise signals are available. The crest factor is usually specified in power and durability tests for amplifiers and speakers.
