how to detect guitar line-in signal?
Hey guys,
I've been working on a project and I'm trying to detect the line-in signal from my guitar. The computer recognizes a signal in Garageband, but if I switch to line-in as input just within the system settings, nothing shows up. Just to test it out, I tried the getLineIn() method in minim and, sure enough, nothing. Im fairly new to Processing, so I'm not sure if there are better ways of getting the signal other than minim, and whether it's a hardware (preamp needed?) or a software problem.
Thanks! cta

what audio interface do you use? does it have multiple inputs? You need to set (in your system settings) your default input to the input you are using for your guitar. I often try with AudioRecorder - if you have your inputs set correctly minim should see the signal
