PhaseChecker for Android

11 things about PhaseChecker

1. Manual mode allows you to run the test signal and flip the phase so you can listen yourself to ensure your sound system is setup correctly.

2. The PhaseCheck app will run a test signal through your sound system to ensure your speakers are in-phase and wired with the correct polarity.

3. You should check the phase of your sound system whenever the wiring has been changed to ensure everything is the correct polarity.

4. Automatic mode will run a series of test signals through your sound system and use the microphone on the device to analyse the results.

5. To run the check connect your iOS device to your sound system so it can play audio.

6. It allows you to play an asymmetrical waveform (ramp waveform), record the sound from each speaker close up and capture the waveforms to then compare them.

7. Phase cancellation will not occur close to the speakers so ensure the device is not too close.

8. When a sound systems speakers are out of phase the sound quality is affected massively.

9. Phase is a difficult concept so full help is available in the app to ensure you get the best results.

10. Ensure the volume is at a comfortable listening level and if possible ensure there is no background noise to interfere with the scan.

11. If possible place the iOS device evenly between the speakers.
