Got pink noise? SignalSuite adds precision signal generator capabilities to your iPhone or iPod touch. SignalSuite’s three advanced, audio-band signal generators produce various types of periodic signals, broadband noise, and frequency sweeps.

- Generate familiar periodic signals, including sinusoids, rectangular waveforms, triangle waves, and sawtooth waves.
- Generate two periodic signals simultaneously, with an arbitrary phase difference between them.
- Generate three different types of white noise and pink noise.
- Generate linear or logarithmic frequency sweeps.
- SignalSuite remembers your signal generator configurations between launches.
- Pan (balance) controls allow different signals to be sent to the left and right output channels when working with the stereo headphone jack or line out.
- All three signal generators can be operated simultaneously.

Ratings and Reviews



My favorite go-to signal generator for the last 5-6 years. Thank you for updating it so I can delete the inferior one I have been using to get by.

Thank You! Great Update


I love this app, always has been my go to. Thank you for updating it and supporting your customers!!! Love it!

Two problems: one small, and one huge


First the huge problem. Signal Suite will not run on my iPod touch (3rd Gen) running iOS version 4.1. As another reviewer has commented: Signal Suite crashes upon launch.

Several months ago, when this program still functioned, I liked it very much. But I did have one small gripe. I needed to set two output sine wave signals that were 90 degrees out of phase. Setting up Signal Suite to output the desired waveforms was a snap. And the signals were phased correctly... initially. But the phase would drift gradually over time. After 15 seconds or so the phase had drifted enough to be unusable in my application of the app. Re-starting the signals would align the phase again, for another 15 seconds.

Signal Suite has many other useful functions, and was still worth the $10 price tag... back when it would function at all. I'd give it 4 stars, if it would run.
