Hey all, I'm just wondering, is the start of this short recording a ground hum loop? It appears to be a weird high pitched whine in there as well... This was recorded on my yamaha psr e-403 keyboard going into my PC via the Phones/Output on my keyboard.. I've ruled out the fact that it's my PC/soundcard by trying it with an amp in a different room away from my PC, but I still hear that annoying whine. Also plugging my headphones into the phones/output port on my keyboard results in that annoying whine disappearing... http://moose.linux-coders.org/what3.mp3 Could a DI box solve this problem?
