I am a long time musician and am new in the world of recording. I am making a solo album and doing it all on my own. I need help with an issue of a high pitched sound that shows up in my recording. I am running Guitar-->Mixer-->Laptop(adobe audition). When i have my head phones in the mixer to hear my tone before i hit record; it sounds great. but when it goes into my computer it ends up with this horrible high pithed buzzing. Heres what i have done: -Its not the Mixer (Sounds good on monitors) -Not the Wires (changed them all) -Sound card (i have tested it with other bad microphones) The only thing i can think is that it is the power of the mixer overcoming my sound card... but that is a guess and if that is true i have no idea how to fix that. I appreciate you guys helping me out. If anything please just sugest things to try out. I really cant think of what else i can do to try and fix this. I decided im not going to record untill i have the sound i want.
