Ok, so I've FINALLY got a firm grip on calibration. I have been able to succesfully calibrate the input and VU meter levels. I needed to have an oscillator so I could send both a -18 and -8 dBm 1 kHz tone. I downloaded one, and it didn't say which dB it sent out (dbm, dbv, dbu?) so I just hooked it up to a voltmeter and messed around with the output amplitude until I got the the right reading on the voltmeter, for both -18 and -8 dbm. Due to the simplicity of the free osc, I couldn't adjust the output amplitude as much as I wanted, but was able to get -18.2 instead of -18 dBm, and -7.77 instead of
-8 dBm. So for each, I was .2 or .3 dBm off.....I calibrated the inputs and VU meters to these slightly off tones. Do you think this is a big deal? is .3 dBm difference really going to change anything? Thanks!
 
man....I know you are new to the whole process, but all I can say is "RAR"........Relax And Record!!! Analog doesnt have to be/shouldnt be exact to sound great!
 
its difficult trying to teach yourself something at first. there are a million questions...once you get through you'll be an expert!

Nope, doesn't matter at all... consider that you nailed it. :)
