Oscillator

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.

Does what it says it will - nothing more, nothing less. Obviously a niche product but it worked brilliantly for what I needed it for.

Just figured out to get below 100 hz - using the 'Edit' button on lower left, type in any frequency you want. Great App!!

I love the app's simple interface and many options. I do wish for a triangle wave option, though.

Good work! Minor UI gripes: it's a bit rough. Still functional, however.

Not a bad app would like to see duty cycles and periods in the future though

This app is great except the sound shuts off when the iPhone goes to sleep!!!! The iPhone's screen shuts off after a few minutes which turn off the sound!!!

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.<br/><br/>One trick I learned is changing waveforms quickly and repeatedly to get a nice trigger effect.<br/><br/>Even though it doesn't have cutoff, you can manipulate it physically by partially and completely covering the speaker on the iPhone.
