* Beat detect sensitivity fix. * Default: 1.0 * ReadMe beat sensitivity min/max. * Beat sensitivity from config or settings isn't initialized. * Smarter position. * Make PCMScale (vol_history) also impacted by beat_sensitivity. * Enhance and clarify Hard Cuts and better separate beat sensitivity. * Forgot one config. * Consistency with defaults. * Even more clear about the default for Beat Sensitivity.
