StereoCheck Audio Test

StereoCheck helps you verify that a two-channel audio system is wired, balanced, and behaving as expected. Use guided listening tests to check: • Left and right channel routing • Phantom center stability • Polarity and phase differences • Stereo imaging across the soundstage • Frequency-specific rattles or irregularities • A summary of your listening session The first three checks are free. A one-time lifetime purchase unlocks advanced tests and the session summary. StereoCheck is designed for practical listening checks, not laboratory measurement. It does not automatically diagnose speaker faults or assign pass/fail health scores.
