Speaker Polarity 4.4

This application serves as a speaker polarity tester, allowing users to determine if their speakers are wired correctly, whether in-phase or out-of-phase. It accommodates a wide range of speakers, including surround sound systems, stereo setups, PA speakers, and any speaker with back-end wiring terminals.

Developed by the same team behind the renowned Audio Toolbox, this speaker polarity tester inherits the reputation of being one of the most precise and dependable tools for such evaluations. The innovative technology that powered the original unit is now conveniently available on iPhones.

This application proves valuable for various settings, from testing home audio speakers and studio monitors to professional contractor projects. Identifying and correcting reversed speaker wiring, a prevalent issue in sound system configuration leading to significant complications, is effortlessly facilitated through this app's comprehensive analysis.

The functionality of Speaker Pop involves detecting a distinct 'pop' signal emitted by the speaker and utilizing DSP analysis to ascertain the direction in which the speaker cone is moving.

By utilizing a standard 1/8" stereo plug, users can easily connect the app to their systems using a typical 1/8" to RCA adapter. Additionally, they have the option to record the 'pop' test signal onto various media such as CDs, DVDs, or other iPods for playback.

Compatible with iAudioInterface and iTestMic accessories, users can further fine-tune their testing experience by selecting a speaker type filter—Woofer, Midrange, or Tweeter—for enhanced reliability at different frequencies.

Upon positioning the phone near the speaker and initiating the test signal, the app promptly delivers results on the screen—'Plus' indicating correct polarity and 'Minus' signaling the need to switch incoming wires for accurate alignment.

As part of its extensive functionality, the app offers stereo and surround test signals for download from its website, designed for easy burning onto CDs or DVDs. Notably, advanced DVD burning software may be necessary for encoding surround files—Toast has been highlighted as a compatible option. For added convenience, test DVDs are also available for purchase on their website.

For those interested in exploring similar audio tools and applications, the developers offer a diverse range of products such as AudioTools—a comprehensive audio and acoustics test and analysis application—SPL—a professional-grade sound level meter for iPhones—SPL Graph—for recording sound levels over time—and a lineup of other specialized apps including RTA, FFT analysis tools, ETC, RT60 analysis app, and Generator—an iPhone signal generator. Expect more innovations from this brand in the near future.
