- The “Invert right” control is meant to expose out-of-phase speakers: the page says the centre image should collapse and bass thin out.
Field notes
The control panel offers Pink, White, 1 kHz, and Music sources, plus a level setting from −40 to −6 dBFS, Left/Both/Right output selection, and right-channel polarity inversion. Its guidance connects those controls to practical checks: crackles and dropouts, gain and line levels, speaker placement, and stereo phase. The page says processing stays in the browser; the Music option currently shows “No track loaded” until a file is chosen.
