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.

What's New in Version 2.4

Added support for Bluetooth audio devices
Fixed a bug that could cause a crash under iOS 8.3 when creating a snapshot.

Somewhat buggy, but finally got it to work.

Initially, I had an issue with turning on and off the channels on this application (I was trying to simulate a phone ringing). It would be nice if the app provider put a "mute" button on the application, and possibly, a slider/function for turning off/on the noise at periodic intervals. There also does not seem to be any about or info screen for this application.
