Hi onhwy. I started a thread recently on Digital EQ, and NO ONE responded! Apparently there are available 24 bit digital-domain pro EQs that, depending upon the type, either allow you to take a digital signal and play with it (hopefully transparently), and more complicated ones with ADC and DACs in them (although you wouldn't want to do this unnecessarily, right?). I haven't the names of these, but I've heard that masterers and other production folk use them routinely. I can easily imagine that you can use one of these to flatten a room or speaker response somewhat, or dial in a spectral tilt, as you like. Using one to "match" a pre-existing signature of an existing analogue pre or amp would be easy, but a little bit like putting the cart before the horse, no? Has anyone out there used one of these pro DSP EQs in a high-end two-channel home system? Ernie.
Digital Modeling of Sonic Signatures
A company called Line 6 has a number of products aimed at electric guitarists. Basically, they are digital, solid state signal processors and/or amps that use DSP to sonically model the sound of specific guitar amplifiers. The sound palette ranges from classic Fenders, stacked Marshalls, clean Rolands and more modern hi-gain, class A designs (Mesa-Boogie). Amazingly, the digital recreations are very accurate. I'm not saying they're indistinguishable from the originals, but the recreations are real close. My question is -- why are no audio manufacturers applying similar technology to recreate, or mimic the sonic signature's of well known high end amps and preamps? I'm imagining an outboard processor that the user could dial in any sound palette they desired, whenever they desired. Would any of you buy a product like this?
