I rather doubt you'll be able to get a soundcard that guarantees frequency responses above something like 32kHz. The main point of such high sample frequencies is to get rid of audible aliasing effects and allow for processing without significant frequency warp when doing bilinear transforms. "Flat up to 85kHz" is silly for audio processing, and 85kHz is just slightly below the Nyquist frequency of 96kHz, requiring quite steep analog filters defeating the purpose of high quality audio sampling. Are there any "audio" cards with 384kHz sample frequency that is more than a marketing gag but actually supported by the hardware? Because you'll have quite a better chance to be in a reasonable quality range at 85kHz if you are not as close to the theoretical limit while being way above what is actually audible. -- David Kastrup _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
