Hello John,
How's it going these days?
Today I'm thinking of CD ouput spectrum measurement using REW and a soundcard.
You know the flat spectrum of a audio source(such a CD device) in a car audio system is important, but I need to know the actural spectrum of it.
I know that REW can do a calibration to the soundcard with a loopback conncetion.
Can I use also a connection below
Or a connection like this below:
And in REW, should I use "making a measurement "->"SPL" the get the spectrum of the CD?
Or I just play a pink noise sound track in the CD and run RTA function in REW, then get the spectrum of the CD output? If this method is better , I can also use SMAART to get a more accurate spetrum curve.
Thank you in advance.
