I'm a lighting guy so please excuse my limited knowledge and vocabulary. The LED's that show the audio level on my highschool's sound board are completely dead. Therefore, I don't know if the signal is peaking(unless i hear it which is rare) or the signal is about to peak and I need to adjust levels. My question is, is there a way to run the signal through an external sound card attached to my laptop running a program to monitor the signal levels? My card is an M-Audio Fast Track Pro.
