1. Like large scale concert PA systems, home theater systems, studio monitors, car audio en even headphones.. - Use a wire to connect your phone/tablet to the Sound System. - Use 2 phones/tablets (one wired for pulse generation and one without wires for measuring). - Copy the pulse files (which can be found in sd-card/PolarityChecker) to a playback medium (cd/iPod) that is able to repeat single tracks. - When the polarity-reverse button "Ø" is pressed (red), the pulse generator plays a negative pulse.

2. A lot of filter-designs that drive loudspeakers have out of polarity components (so for instance the high frequency speaker CAN be opposite polarity to the low frequency speaker). - Try to measure as close to the speaker as possible (and away from bass-ports). - dBFS means "Decibels relative to full scale".

3. When measuring "passive filtered" speaker cabinets (for instance when you've got one amplifier driving your low and high speaker at the same time), it can be useful to select a frequency dependent pulse to isolate the speaker you want to measure.

4. With this app you can turn your android device into a "polarity popper" and check the "polarity" of a speaker, whether it first moves forwards or backwards (often mistakenly named "phase", which is also time and frequency related).

5. So the measurement should give opposite readings! (equal to playing an INVERTED_pulseXXXX. - Avoid CLIPPING the microphone, this could corrupt the measurement. - Adjust the threshold, so the checker doesn't get triggered by background noise. - Try to measure one speaker at a time.

6. So 0dBFS is the maximum soundpressure your device is capable of handling without distorting (clipping). - Using a different pulse signal CAN give opposite readings, due to loudspeaker filter designs.

7. Polarity Checker can be useful for testing almost all sound sources.

8. A loudspeaker should have the same polarity as it's "friend on the other side" when measured at the same position/distance.

9. For a good working Sound System it is essential that all loudspeakers are wired correctly.

10. If possible mute all other sound sources.

11. This also counts for multiple speakers which should be doing the same (a cluster of multiple subwoofers for instance). - Red is NOT bad!!

1. i just have doubt that my sound of my new system is not good and i search online and found this awesome app and check the polarity using this app and make them same for every speaker now my sound system is producing very good sound with great base effect.

2. After installing this it took about 2 minutes to diagnose polarity problem because of non-matching adaptors, and all fixed and checked within the hour.Save time and effort to check the polarity of my sound system this application is really useful.

3. Just park somewhere quiet.Works quite well! Was able to diagnose a car audio install that didn't sound quite right - one speaker wired "not like the others".

4. Both the wolfer and the tweeter, so, this was an easy fix at the crossover.Had sound issues in my vehicle with a shop installed AC lc7i stock head unit.

5. For 5.25 car speakers, in a motorcycle fairing in my case, just leave it on the full range setting and let it run, holding near each speaker.

6. i recommend this before visiting any sound specialist i'm pretty sure you can fix the problem by identifying it by your self which save you time and money.

7. another useless audio app, I have yet to find an audio apps that can produce any uselfull info or perform any real tests that can be used to make adjustments to correct any issues.

8. I had replaced the speakers in my car and couldn't get it to sound right.

9. Could do with some notes or instructions within the app though - make sure you read the instructions on the install page here, even if you know what it does...Dirt simple, absolutely works.

10. Simple, dirt simple.Nothing fancy but going by the green good, red bad method works well.

11. I just found out that my right front newly-installed speakers were out of phase.
