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).

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.

well, the RME babyface claims +-1dB in the range of 5Hz - 92kHz.
i know that the UA-55 is used by people who have no idea whatsoever
about audio (and are no audiophiles either), but still require the
record sounds in the 50kHz-85kHz range. so i figure that card would be
ok as well (if it did support 192kHz under linux)

sure. that's why i was asking on the list.

Hi,
the Focusrite Scarlett 2i2 2nd Gen (does cost 129,-€ in Germany), respl.
the complete Focusrite Scarlett series of the 2nd generation could do
192KHz. I'm using a Focusrite Scarlett 18i20 2nd gen, but IIRC I never
used anything else than 44,1 KHz and 48 KHz with the Scarlett.
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, while IIRC there's no noise floor
issue at 96 KHz with this card or even when using a Terratec EWX 24/96
at 96 KHz (96 KHz is the highest sample rate of this particular
Terratec).
Regards,
Ralf

Of course the noise floor increased- it's
double the bandwidth!
But all that extra 'noise' is going to be way outside the audible range.

IIRC it was audible, but I might be mistaken. Your claim is, that the
additional noise is in a frequency range we don't hear, it doesn't
affect the audible frequency range? The meters just show the sum of all
frequencies? Maybe. Perhaps I'll test it again, but since I've got an
incurable tinnitus since this year, I anyway might be unable to notice
some kinds of nuances anymore.

It reminds me of "rats in NYC:

Never having measured or recorded it myself, I found it interesting that
the spectrum around ~80kHz is rather quiet, even in otherwise noisy
urban environments.

It's said that in-ear monitoring for Vogons reading poetry is a good
thing, at least better than monitoring by speakers, so that every body
else needs to hear it, too. OTOH the Vogons poesy's beauty might get
lost in the human's audible spectrum.

The Steinberg UR242 could fit the specs and is fairly cheap.
I had the smaller UR22 and it was working pretty good until it developed
nasty
clicks that i never found the source for (independent of the system i
used it with)

That's only 4 kHz. Bandpass and mix with a 70 kHz sine and you get
7 to 11 kHz, any normal soundcard will handle that.

I tried the RME RayDAT with an external converter (Ferrofish A16 Mk II)
- the RayDAT works fine on Linux at 192 kHz also at low latency (round
trip delay about 1ms), and with the A16 you can get 4 channels, however,
they don't have phantom power or mic amps built in. Total cost is about
1.500 €, but if you have converters lying around the RayDAT is "only"
600. I did not measure the frequency response, but if you are interested
I could do next week.
