    Hola Arnold,

    el tamaño de FFT determinará la frecuencia de resolución FR= SR / FFT (ejemplo 48000/16384 = 2,9Hz) y la constante de tiempo TC= 1/FR o lo que es lo mismo TC= FFT / SR.

    Un saludo

    Hola Carlos,

    Es normal que las vías te lleguen al punto de medición con diferente tiempo.

    Para poder separar el rango de frecuencias para cada vía, el altavoz está usando filtros, que a no ser...

    Hey Rasmus,

    If it is simply a problem with smoothing, the same response is shown with less data.

    Hi all,

    Excuse me sometimes I'm lost in translation.

    From my point of view, it is always a compromise, our maximum value will always be the clip of our amplifier. if we use such a 18dBu maximum...

    Hello,

    I agree with Ferrit, if we modify the amp, we are modifying the voltage gain, then we must recalculate the input sensitivity for the calculation of the limitation.
    I think so., But I can...
