I did some tests just the other day with my Technics tape deck and BSR equalizer (yes, from DAK, no straight-wire-with-gain flames, please) to determine which noise reduction works better for me. I often use the Equalizer to ``improve'' the frequency response of the tape deck, and I wanted to see how Dolby C and dbx reacted to that, too. My results were not conclusive, but... 1. In recording silence, dbx was quieter. 2. In recording music with quick dynamics changes, the dbx ``breathed'' terribly, worse with the equalization than without it. Dolby C did not breathe at all, as far as I could tell. 3. Dolby C seemed to work well with or without equalization. 4. In taping music with great dynamic range, the dbx gives you a bit of an edge. I have never saturated a tape when using dbx. 5. Dolby C is slightly quieter in the very soft passages, I think. It also seems to have a slightly ``different'' sort of hiss. One that I find a little less annoying than the dbx-flavor hiss. Hope these results are helpful to somebody. I make most of my tapes with dolby B anyway, because my car and office equipment have no noise reduction at all. Listening to dolby-C or dbx tapes without the appropriate decoding is irritating. -- ...nz@wucs (ECL - we're here to provide superior computing) {seismo,ihnp4,cbosgd}!wucs!nz OR nz@wucs.UUCP "We can fit an infinite number of wires into this !@#!$?* junction box, ... but we don't do that far in practice" London Power Co.
