Description

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.

Works great.

Always been a great app. Works flawlessly for me.

Simple but useful

You have 3 waveforms and noise. Frequency, pan, and volume are the parameters. The slider range for frequency can be changed to virtually anything. I set a one octave range between 300hz and 600hz so I could have higher sensitivity. I later changed the max to 6000hz and the iPhone played it fine.

One trick I learned is changing waveforms quickly and repeatedly to get a nice trigger effect.

Even though it doesn't have cutoff, you can manipulate it physically by partially and completely covering the speaker on the iPhone.

Great to use with an equalizer

A great app to smooth out the frequency response of your sound system when used with an SPL meter and an equalizer. Also useful to help set your crossover points. A very good tuning tool for a buck. I looked at the sine signal on a scope; very little distortion, but some high frequency noise was detected. This noise probably originated from the probe cable or the ipod itself. This low noise was inaudible to me.
