iFunctionGenerator

iFunctionGenerator turns your iPhone, iPad, or iPod Touch into an audio function generator.
You can have up to 20 generators, each operating at a different frequency. 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. This lets you build a library of settings, and quickly load the desired settings.
