Not exactly, I thought about Tascam US-122 PRO USB 2.0 SOUND CARD, for exampleYou should probably be more specific as to what cards you're interested in.
Is it the Tascam US-144 and the M-Audio Fast Track Pro?
Sounds good ... I agree with you, not sure if expensive device is a must...These are fairly expensive soundcards, both with XLR mic preamp and phantom power. Is that a must?
REW will operate with very inexpensive cards and an SPL meter if you're not looking for high end...
Thank you to your advice, I appreciate your feed back.Definately get the calibrated mic from Cross Spectrum. I got an uncalibrated ECM-8000, then when I read about the spread among samples and when I recently upgraded subs, I got the calibrated one. There was quite a difference between the calibrated mic's curve and the generic one posted here (to be fair, it was based on one sample - Sonnie's I think.)
