Hello!

I'm looking for recommendations for (economically priced) sound card
with 192 kHz sample rate that is flat up to 80 kHz. It should
preferably be external (USB). Any suggestions? Anyone using one that
can be recommended?

Thanks!

It's PCI, but the M-Audio AP 24192 qualifies.

Also, check out eMu. They have reasonably-priced high performance audio
interfaces.

Why...... are you making music for your dog.
No seriously, what are you going to use it for since 192 KHz is a must.

Do you know if these actually go up to 80k? Because there are
apparently lots of cards that have 192 kHz sample rate but are
designed for audio and the built-in filtering starts rolling of at
20k...

I want to see the spectrum of a 80k signal, but I don't need it to be
measurement quality...

If you want to see what a signal looks like an USB Oscilloscope might be a
possible choice.

A large bandwidth is useful for some non-strictly audio applications
like FM stereo/RDS encoders like Stereo Tool (freeware except for a few
functions!) or other signal processors.

You've been given bad advice I'm afraid. I have the Emu 1212m...
decent card, but HF roll off below 20Khz.

If you really want that kind of bandwidth, and you actually want it to be
accurate and repeatable, you're going to have to pony up for the National
Instruments hardware, or something like it that is designed for instrumentation.

If you want to see harmonics of a 80kHz signal you need a bandwidth
much, much over 192kHz. The 2nd harmonic is 160kHz, the third is 240kHz...
If you need to see what is located under the 80kHz signal it is a bit
different.

Yes, although its not uncommon for there to be a bit of a roll-off, say -3
dB in the last octave.

There are a lot of audio interfaces that report to the system that they
handle up to 192 KHz. However, they just downsample and upsample, probably
in software. However, the spec sheets for these products typically tell the
true story about response up to 22 Khz or so.

By who? Who recommended the Emu 1212m to you?

I have the Emu 1212m... decent card, but HF roll off below 20Khz.

This seems to be true, based on these results.

I notice that these have been posted since 5/2004 and came up almost
instantly in google searching.

Did you do your homework and buy the product anyway?
