Polarity Checker APK para Android

Polarity Checker is a free Android application designed for audio enthusiasts and professionals. This tool allows users to determine the polarity of speakers, ensuring that sound systems are wired correctly for optimal performance. The application is particularly useful for testing a variety of audio sources, including concert PA systems, home theaters, studio monitors, car audio setups, and headphones. It provides a straightforward interface for users to assess speaker polarity and troubleshoot wiring issues with ease.

The application offers two primary measurement methods: using a microphone or a signal generator. When utilizing the microphone, users can select a frequency-dependent pulse signal to be played through the speaker while measuring the sound pressure. This method helps identify incorrect wiring by displaying results directly on the screen. Additionally, Polarity Checker allows users to save measurement results and play sounds, enhancing its functionality for ongoing audio testing and calibration.
