I doubt it, if an equalizer is what you want. A multi-band compander would be a compressor/expander, kind of like the dbx boxes of yore (or perhaps still of today?). They're for increasing (if you have some sort of compressed source and want to "open up" its dynamics) or decreasing (if you want to track steadily nearer to maximum loudness, for example) the dynamic range of the signal. They began being implemented with multiple (most notably three, in the dbx 3BX) frequency bands in an effort to avoid audible "noise pumping". (The latter would be audible if, say, a big bass pulse caused the signal to be amplified, and the original had some steady high-frequency hiss -- the hiss's volume would be modulated by the bass expansion if they weren't sequestered in separate bands.) _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
