Why do we use passfilters for signals of the anaog domain that are anyway inaudible? For example, speaker could get stressed by inaudible signales and the output could cause unwanted side effects. Or just imagine another issue, direct current. Direct current is inaudible, but direct current of high enough energy could burn the speakers, so we also need a protection to prevent against this issue. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
