hi all, i'm looking for a soundcard that can capture at 192kHz, preferably 4 channels (at this samplerate), with phantom power. the frequency response should be fairly flat up to 85kHz (i'm mainly interested in the frequency range between 77kHz and 81kHz). afaik the roland UA-55 (Quad-Capture) both supports the required sr and its anti-aliasing lowpass doesn't kick out my payload.. the UA-55 seems to be discontinued, but i guess that the UA-1010 (octa-capture) would also have suitable hardware (and is able to capture 4 channels @ 192kHz). however, from what i've found on various forums, both devices only have basic support on linux; esp i've read that they are only supposed to run in 44.1kHz, which - for my use-case - is a show-stopper. the UA-1010 is about 500€ which is nice enough (i don't think the project would be able to afford a 1000+€ soundcard). gfmdfx IOhannes _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-user

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,

Are there any "audio" cards with 384kHz sample frequency that is more> than a marketing gag but actually supported by the hardware? Because

A long time ago I tested 192 KHz with my RME HDSPe AIO. The noise floor increased that much, that at least with this card, 192 KHz for my taste are unusable for audio productions,

Aliens at IEM?
