I am about as lost as I can possibly be with Spectra Plus. I installed the software and in my "view configuration" my sound card is recognized. I connected the RS spl meter to my sound card line in. Line in recording is at max input. I clicked record in Spectra and played the AVIA sub sweep and stopped recording at the end. I saved the file to .wav.
Now how do I chart the response? I see bars at the bottom of the spectrum when I play the file but it shows response from 20hz all the way up to 20khz. The AVIA signal only goes up to 200hz. It don't look right. The bars are lower at 20hz than they are at 20khz.
I've got to be missing something here. Do I have to configure for frequency response? Should I use post processing to view the file? All I can see is the bars moving like crazy while it's playing.
Please help. Can someone walk me through a step by step procedure in setting up Spectra configuration (or copy and post your "view configuration" here)? And then walk me through a step by step charting? I can't make sense of the help in Spectra.
If I'm asking too much I understand.
Thanks,
SP
