Good C-Media USB sound card?

I owned one, and still, for some reason, I thought that he had spelled it wrong.

BTW, Vlad, old boy... FUCK YOU for jumping on the Larkin's Retard Crew bandwagon.

And then you stuttered it three times, so maybe you are going senile as well as the bandwagon stupidity.

Perhaps I didn't make this clear, but the recorders work by themselves OR as a USB sound card. My point was I could record without a PC and with a PC to determine if connecting the PC caused artifacts. The noise from a PC can set into your circuitry.

These oversampled converters often share a lot of DSP between channels to reduce the cost, but if designed property they will act as if the sampling is simultaneous, with of course some significant delay.

Well obviously you need to do a search to get a price. The amplifiers for the H2 and H2N are very quite for the built in microphones. They suck on the external microphone inputs. I don't have the H4 for comparison.

You really want the H2N over the plain H2 if you are using the line input. The H2 feeds the line input directly to the ADC, i.e. no level control. The H2N allows the line input to be attenuated.

I've used them for nature sounds, outdoor concerts, etc. My expectations are all that high for those purposes. I've also used them to record scanners. The VOX feature supposedly works well now, but with the cost of flash so cheap, I just record everything and use Audacity to "trim silence".

The cases are plastic and thus not shielded all that well. I have had radar get picked up by the internal microphone amps.

I've stashed the recorders away from people and let them catch nature sounds. Sometimes entertaining if a bee starts buzzing around it. You can pick up bird calls.

You probably want to get a dead cat for it if you don't want wind noise. For example:

I thought you wanted an ADC, not a DAC.

That is the beast I used to have. Some of the reviews complain about the drivers. Well duh.... . I will admit it was fine under linux until it broke.

Works fine for the sigint. I use to do demodulate digital signals off of radios. The specs aren't great, but the cost sure is, and the metal cases can take some abuse. The A/D on C-media cards is about 90db SNR. I am dealing with signals with 40db.

NI data? The freaking SB card was only 70 bucks. I don't see the comparison at all.

I need lots of channels. They don't have to be great, but they need to be plentiful.

OK I went looking for a price but found nothing right away. I bought a "natures window" outdoor mic with amp/speaker for my wife several years ago. She keeps it on continuously during the spring and fall.

(We must have version 1.) I made a wind shield from a bit of gauze and 1/2 of a plastic pop bottle.

I need both. The output can be fairly crude and I only need one channel. The ADC needs to be superb and both channels must remain in perfect lockstep. Not clock dither, all squeaky clean. Because I'll do phase measurements between the two. 96k would be nice but 48k is ok.

But I could not find any datasheet:

This time I made sure that I have information which chip is in the sound module and also that I have its datasheet in hand before ordering. That allowed me to ascertain the sanity of the concept at least to some extent. It's the PCM2902, old but apparently quite robust. So I have ordered the Behringer UCA202 that Lasse suggested. Should be here next week.

OK. The Via can use an external clock. And M-Audio DAW hardware is all Via Envy24, and (to me) it is totally transparent.
