Because the description of the Peak Detector talks about <factor> i think the <TH Factor Rise/Fall> is a factor meaningfully greater than <1.0> ? The alpha seems to weight the input values, which are be computed for the average, but i think it also results in a average computing of a longer time ? The alpha should be meaningfully 0 < alpha <= 1.0 . Is this correct ? A other Problem is that the Peak Detektor freezes the graphical elements, but i don't get any overrun/underrun. I have got a decimation of 256 and a sample_rate of 250k. Are there known Problems with the Peak Detector ?
