I bought a spectrum analyzer(option #5) from http://makeitlouder.com/products_soundmeter.html i installed true audio program but.... my problem is calibration with sound card and mic i read manual and do some instruction
1.connect line in to line out with Y wire.(below pic)
2.At TrueRTA Generator Bar, select a 300 Hz sine wave and Enter -10.0 db for the generator amplitude and turn the generator ON
3.my multimeter says 1.230 volts
4.i enter 1.230volts in line out and line in calibration blank
5.then enter mic calibration from manual(manual says calibration:92.5 db/milivolts @ 148.35 db) in spl calibration blank this is right?? why my true audio has only 1oct rta resoluion??
excuse me for bad writing english
