Signal Generator


Open iTunes to buy and download apps.


Turn your iPhone into an amazingly powerful signal generator and produce perfect sine, cosine, square, triangle or sawtooth waves. You can even generate white and pink noise with this versatile App.

This “must have” tool is perfect for any audio-related testing or calibration:
- Test your headphones or speakers
- Set up and calibrate your surround system
- Tune an instrument
- Test your hearing: What frequencies can you hear? (And not hear?)
- Or simply generate annoying noise to drive someone completely nuts ;-)

- Sine, cosine, square, triangle or sawtooth waves
- Pink or white noise
- Direct frequency input or dial wheel (sweep)
- Frequency range between 20 and 20000 Hz
- Current waveform is shown on your screen
- No samples - all signals are generated in real time
- Channel switch (left, right or both)
- It’s high-tech, multi-frequency fun at its best!

What's New in Version 2.1

Customer Reviews

Great app for those getting started in DIY Audio

I'm just getting my feet wet building my own speaker enclosures. This program works very well as a testing tool. I was up and running in seconds. The interface is very well made. The program works great. I went and installed all three apps that I thought would meet my requirements. This app wins by land slide. I'm still trying to understand how to use the (R) button properly... I'm sure ill get it figured out soon enough.

Almost the Perfect Diagnostic Tool!! Jersey Jules

Update this potentially great Freq. Generator to accommodate the "FULL Frequency SPECTRUM". I was so pleased when I first started using the app until I started turning the potentiometer up a few kilocycles and realized it was missing huge chunks of frequency range! Where's the other half of the spectrum?
Find your pride and make this (already on the way) tool, complete & the best that it can be, and I'll do my part! * * * * *

For the money. Bar none. Worth the extra 0.99. (Any review less than 5 stars needs to learn how to use the app- EVERYTHING works ok).
