Use QuadWave to generate up to four sine, square, sawtooth, or triangle waves. Learn important physical concepts. Make interesting sounds. Annoy your friends, family, teachers, fellow students, or co-workers. Pick a sound between 20hz to 20,000Hz, the range of average human hearing, using a simple, sliding control and selectively activate or deactivate tones. To put it differently: QuadSine may be used as a signal generator OR a digital noise maker. Physics and music teachers: Demonstrate interference, beats, and harmonics to your class.
Please Note: If you are unable to hear sound please be certain your speakers are turned on; this application respects your system-wide speaker settings.
