The Test Tone Generator (TTG) turns the PC into a function generator for testing or demonstration, sound tuning, education, for sound effects and other purposes. It can produce constant or 'swept' test signals in real time. You can also save the signal as a .WAV file, e.g. to burn a test tone CD.

You can also run scripts of test tones and save 4 memory presets of fixed or sweep test signals and supports multiple sound cards.
