Oscillator is a simple and rough audio generator application which has the following functions. You can use it as a test tone and play it as a strange musical instrument.

- Four waveforms. (i.e. sine wave, square wave, saw wave and white noise.)

- Exponential Frequency control using the slider.

- Frequency numeric input using the software keyboard.

- Equal distance panning control using the slider.

- dB style amplitude control using the slider.

- Sound output on/off button.

- All sliders and buttons are multi-touch controlled.

Please note the limitations below before you purchase/use this application.

- The frequency control is not effective with the white noise oscillator.

- The panning control is not effective with an iPhone internal speaker because it is monophonic. Use headphones or stereo speakers.

- The audio output might be interrupted on a keyboard input, a view change and so on.

- The accuracy of the audio output is not very high but it is reasonable.

What's New in Version 2.0.0

- iOS 9 compatible
- New randomize function

5/5 stars

Works just right.

I wanted a simple sine wave generator so I could informally test my audio gear (and my own hearing). This program does the job just right. Nothing fancy, works great.

4/5 stars

Simple, Functional, Wonderful

Does what is says. If you narrow the Q, you get a more accurate tone. Yes, pink noise would be nice. If you are looking for "white noise machine" this will stop generating when iPhone screen sleeps.

5/5 stars

Great App

If you're looking for a frequency generator this is it. And for the other reviewers, what do you expect an ocillator to do! This app does everything it says and you can edit the frequency range too! Good buy!
