This app is a speaker polarity tester. Find out if your speakers are wired correctly (in phase or out of phase). Test your surround speakers, stereo speakers, PA speakers, in fact any speaker with wiring terminals on the back.
This speaker polarity tester was designed by the same people who built the Audio Toolbox, and the polarity tester in that unit was known as the most accurate and reliable polarity tester available. Now that technology is available in your iPhone.
Use this app to test your home speakers, recording studio monitors, or as part of your professional contractor work. Speakers wired backwards are the most common error in sound system setup, cause big problems, and are easily corrected. This app will give you the answers, no matter how difficult the wiring may be to trace.
Speaker Pop works by watching for a proprietary "pop" sound from the speaker, and doing DSP analysis of the sound to determine if the speaker cone is moving in the correct direction.
As long as you use a standard 1/8" stereo plug, you can use any normal 1/8" to RCA adapter to get the signal into your system. You can also to record the "pop" test signal to a CD, DVD, or another iPod, and play this signal through your speakers.
Works with iAudioInterface and iTestMic.
Select the speaker type filter, Woofer, Midrange, or Tweeter. This selects either a 125Hz, 500-2000Hz, or 8000Hz filter, to make the readings more reliable.
Once you have the test signal coming out of the speaker, position your phone near the speaker (we suggest you flip it over to point the internal mic directly at the speaker -- the display will flip). In a few seconds you will get the reading on the screen, either a Plus or a Minus. Plus indicates correct speaker polarity, Minus means you need to swap the wires coming into the speaker.
We also have stereo and surround test signals available for download from our web site which are ready for burning to CD or DVD. See our web site or for more information. Note that iDVD will not burn encoded surround files, a more advanced DVD burning authoring program is required. Some folks have had success with Toast. We also sell test DVDs on our web site.

Works well, but a big buggy!
I purchased this to help determine the correct polarity for my DIY electrostatic loud speakers. The way I got this to work was to download the audio click from their download section and play it through each speaker tested. This being said it seemed unreliable at my buddys apt when tested on exact similar speakers (we believe it was likely getting reflections from the adjacent walls). When I tested this at my house it worked like a charm…(since I have diplole speaker I it changed consistanty when moved from front to back confirming it was functioning properly) ultimately confirming the speakers polarity was wired incorrect.
There is hot much in the market for an inexpensive device to perform such a task, therefor I am grateful it was available as it made a HUGE improvment to my system!!!
P.S. don't hit the information icon it will crash!
Best $5 i’ve ever spent!!!
Moved into new house with speakers built in everywhere to the ceilings and walls. No idea how the wires are connected, and i’m not about to go around removing each speaker from the wall and ceiling to see how they are attached (i tried one one, but they are very difficult to remove).
I needed to know the correct polarity so that I could correctly calculate the impedance of various series and parallel circuits of speakers with the amp so i didn’t overload it (in addition to them having optimal sound).
The builders of my house did not seem to follow any sort of convention or pattern when installing the speakers and connecting the wires, unfortunately. Using the app I was able to see that approximately 25% of my speakers were wired backwards and I simply matched this backwards wiring on my wall plate to ensure that I have the correct polarity everywhere. This app save me hours and hours and hours of difficult work and I will be forever grateful!!!
Quick and easy
I ran the WAV click file from their website through my stereo (using my iPad), then held my phone in front of each speaker to check polarity. 3 out of 4 of my speakers were negative, so I reversed the wires on those. Very quick and easy.
