sweeps or noise waveforms using a Windows computer
with a sound card.

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.
