Running a cheap dynamic mic through xlr into an M-Audio Fast Track, then to Mixcraft.
Generally speaking, I get a nice clean recording this way. However, in certain environments, it picks up an electrical buzz caused by some sort of ground loop or other interference. Unfortunately my dedicated music room is one of those environments.
It largely dissipates if I unplug my laptop and run on battery power, but not entirely.
Any thoughts as to what I should do? If a hardware replacement is in order, please make economical suggestions. However, what I would really prefer would be something that doesn't cost more money.
I thought maybe a good gate vst could take it out. If I run it during recording will it eliminate the buzz? Running it after recording only takes care of it during the parts where I'm NOT singing. It's not worth it to me unless I can get rid of it altogether.
Another thought - is there some way to add additional shielding to my M-Audio device?
Suggestions? Thanks!
