We did try processing the signal on computer using an expensive music software program, but it only reduced the hiss on the high pitch signal but not on the low pitch signal (or was it vice-versa), which accomplished nothing and actually made the problem stand out even worse. Having been in numerous recording studios over my band's past 23 year career, I KNOW I've seen DBX rack-mount units in some of them, so I KNOW they exist SOMEWHERE under the rainbow. I didn't just dream them up. See if you have any luck at music stores, especially those that sell recording equipment. One about 2 miles from here is called, Piano's & Stuff. I'm sure they have an online site, but I don't know the addy. Another I get adverts from at least once every other week is, zZounds.com, in Chicago. Yes, 2 Z's at the beginning, first one IS lower case, but I don't think it matters when you type in the addy. Also, see if Tascam/Teac has a site. They might be able to help you out with this. I KNOW there's some pretty good noise reduction equipment out there somewhere, because I've recently been getting some cd's and albums of old recordings that should have lots of noise in them and DON'T! So, somebody's got some good stuff for such things out there. I just finished listening to a new Captain Beefheart "bootleg" (I think) recording of some live shows he did in the `70's. They sound like someone took a portable tape recorder into the various venues and recorded the band from the audience, not the board, and there should be lots of noise on these tapes, but there isn't. Some of the filters I have on the puter are okay, for the most part, when the sound in the recording is quite loud, but when it gets quiet, the filters are compensating so much that they make the music sound like it's being played under water on a turntable with a scratchy, old a sewing needle in the tone arm. So, I don't even use them unless I absolutely have to. I don't yet know how to use an EQ, but, if I can get away with it, through trial and error, I'll use that before I use those filters.
