I'll be honest, I'm not particularly well-versed when it comes to this stuff so even though I'm going to try and be as specific as possible, I'm sure I'll probably leave out a ton of necessary info. Here's my problem... There's a very annoying hiss present in every single thing I record. Doesn't matter which mic I use or where I'm recording to. I first noticed it with an Audix shotgun mic and a Canon HG20 camcorder. I heard that Canon's have notoriously noisy pre-amps and thought that might be the problem. Then I had to use an Olympus VN-6200 recorder to do some interviews and had the same mic plugged into it. Same problem. I tried using a Rode Video Mic on both the camcorder and the Olympus and the results were the same. Recently, a friend of mine asked if I could help them put together a very low-tech podcast just to test the waters. The major road block is this darn hiss. I hooked up the Audix and Rode shotgun mics to a Toshiba laptop and a Netbook and used Audacity to record with. Same old hiss. What really sent up a red flag though was that the hiss is there before the mics are even turned on. If Audacity is recording, the hiss is audible in the headphones. Same goes for the VN-6200. All the devices have new batteries. I've tried different cables. I've tried different headphones. It doesn't matter. I'm going out of my mind here. Any ideas on what the problem might be? To me, it sounds like the mics are still working properly - there's just this whole other layer of interference (or whatever it is) already there. Again, I'm sure additional info will probably be required and I'm happy to provide it.
