    Hello Johannes,

    • Peak Offset is a hysteresis that is the rate of the Class-H trigger offset. Keeping the default values is recommend.
    • Smooth time constant is the alpha coefficient for the smoothing filter on the audio envelope, this parameter enables a smooth transition from the initial PWM level to the final PWM level.
    • Max Detect Sample are the samples used during audio signal level detection. The Max Detect sample time = (Max Detect Sample)/(sample rate) in ms

    best regards,
