That could cut down on conversion delay and phase artifacts. Whether this is actually done, I am skeptical: high-quality A/D converters have the filtering and downsampling stuff integrated and I doubt that they have a fast unfiltered parallel high-rate side-channel available. Here too, "This is based solely on my thoughts, no evidence. I've never worked with a digital mixer." is applicable. -- David Kastrup _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
