DBX is a form of Dolby noise reduction. Most things recorded in the past 15 to 20 years have used it. Dolby A, B & C each progressively get rid of more and more noise from a recording, not so much pops and scratches from banged up records, I can do that here on the puter, but it get's rid of (dare I say) inherent noise produced by the recording deck or some other device. DBX goes a step further and actually gets rid of tape hiss itself! A, B, & C don't do that. Tape hiss comes from the tape itself "scraping" away across the heads on playback or record. If you have a recorder that has DBX, put in a completely blank tape and play it through your stereo quite loud without using the DBX function. From the time you hit the play button you'll here a hiss come through the speakers. Now, turn on the DBX and listen to the hiss vanish. To demonstrate where the noise comes from, just rub your fingers up and down on your arm. Hear that hiss? That's basically the same thing you hear when the tape crosses the heads. That's what DBX gets rid of. However, now that today's stuff is mostly being recorded straight to computer via programs like Pro Tools, there's no longer much of a need for DBX because there's no tape being used. It's just digital information now.
