Each generator can be one of the following types: • Sine Wave • Triangle Wave • Sawtooth Wave • Square Wave • Pink Noise • White Noise The volume of the left and right channels can be independently controlled, and may be set using either a slider for ease, or direct entry of the volume, for maximum precision. The relative phase of each channel may also be set. Frequencies from 1 to 20,000 Hz may be entered. The phase can vary between -360 to 360 degrees. The volume may be between 0 and 100 percent. The mute button makes it easy to quickly silence the audio generators. You can take snapshots of the generator settings.
