What USB sound card to use for frequency measurement?

[wonderfulaudio]

Hi,

I was using Behringer UCA222 for frequency measurement, but recently learnt that it has poor channel separation. I verified by using a signal on left channel and connecting and amlifier/speaker on the right channel. I could hear the test signal from right channel, even though it was faint.

So, what better USB sound card do you guys suggest for frequency measurement?

Thanks in advance,
Warm Regards,

How about something decent from an established manufacturer for a few rupees more?

hi thank you for the very interesting thread Could shorting one input work ? you can measure the channels separately
Do you have any THD+noise graph of this card maybe ? what are you using as signal generator ?

I am wondering how poor channel separation prevents frequency measurement? I can see how it might have a tiny effect on phase measurement in carefully engineered set-ups, but not average frequency.
