Wizard says it’s great. More power out of your apple/audiojack device if only using first channel.
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.
Full function, intuitive, easy to use. Nicely designed.
