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. ## iFunctionGenerator Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple127/v4/b5/9c/5a/b59c5ae8-b5fd-016a-3e93-99e88c718d32/mzl.nithniwz.png/960x640.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple117/v4/68/dd/ab/68ddabfc-8c99-eb34-53a6-42d3bb97fd19/mzl.zjpamfsf.png/960x640.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple127/v4/e6/a5/b7/e6a5b752-24af-183b-d13e-dc4052f4ab38/mzl.uirmodfe.png/960x640.png) ## iFunctionGenerator Rating Breakdown in United States - 5 stars: 7 (78%) - 4 stars: 1 (11%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (11%) ## iFunctionGenerator Reviews in United States ### *---- "Doesn’t work with iOS 13" Do not download. Reporting to Apple. -- Awsomgaz33, 2020-02-08 ### ****- "It does what I need it to do ... and very well." 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. -- LumberDennis, 2018-05-28 ### ***** "Great app" Create your own TRUE binaural beats! Great app for us geeks! -- soundgoddess, 2017-06-27 ### ***** "Excellent app." Full function, intuitive, easy to use. Nicely designed. -- GuruDave, 2016-08-13 ### ***** "Easy" Easy to use and adjust. -- Fiddlebill, 2013-03-18 [View all iFunctionGenerator reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## iFunctionGenerator Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Hong Kong SAR China | Utilities | #105 | ## iFunctionGenerator Discovered Keywords -
