iFunctionGenerator

Do not download. Reporting to Apple.

I needed a simple stereo frequency generator to produce two closely spaced audio sine-wave frequencies in order to demonstrate the “binaural beat” capability of our human minds to perform a differential frequency analysis of two discrete audio signals and present the differential to us. This app does a beautiful job of this. I took one star away because it does have a minor bug of occasionally locking-up (which killing and re-opening it fixes), and the physical interface is real easy for me to “fat finger”. In summary, this app has both the precision and the flexibility to do exactly what I need it to do, and I am very grateful and pleased to have found it. BTW: The app produces discrete left and right signals with no mixing ... IF you are taking the signals directly out of your phone’s earphone port. If you are listening to the output via a bluetooth device, then you are going to hear a whole bunch of channel mixing. This is not the app’s fault.

Create your own TRUE binaural beats! Great app for us geeks!

Full function, intuitive, easy to use. Nicely designed.

Easy to use and adjust.

1. VERY poor stereo seperation. Left and right tones bleed together. 2. Cannot generate different waveforms for left and right channels as stated. A non-functilnal waste of money.

I bought this by accident, I was looking at it and had no idea that it wouldnt be free but to be three dollars! Kidding me??? Horrible app for three dollars

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.
