FAQ
Can I feel sub-20 Hz energy?
Most laptop speakers roll off far above 60 Hz; pair this tool with real subwoofers or large monitors for meaningful results.
Overview
Bass Test reproduces logarithmic ramps like the KeyboardTester modal: exponential ramps update overlay badges continuously while RMS-driven canvas bars illustrate energy creeping up the audible bass ladder.
