HELP with Amp Modeling

Started by Wayne Preis November 12, 2004
I'm hoping that someone here can help me. I'm looking for a library of
sounds for a guitar processor. I'm trying to build a battery powered
processor using Analog Device's Blackfin chip. Does anybody have any
suggestions on where to begin looking? Thanks so much, WP

ADI had an app note on their web site for audio effect programming on the 21065L, which is a 32bit fixed- and floating-point DSP. Perhaps there is something similar for the Blackfin: http://www.analog.com/processors/resources/technicalLibrary/appNotes.html. Also check out harmony central (http://www.harmony-central.com) and music-dsp mailing list archives (http://www.musicdsp.com) for effects programming. I'm not sure how you intend to model the amp. Do you want to simulate actual tube saturation and speaker cabinet reflections (like the Roland VG stuff)? Or are you happy with a crunchy sound (= eq + limiter + distortion)? FWIW Regards, Andor
Andor, thanks so much for replying and for the links. I'm looking for
something that would probably be closer to the Roland stuff although
it really comes down to great sounds that are musical and feel right
when you play. I need a variety of tube amp emulations along with
their overdrive and distortion characteristics and effects like
chorus, phasing, tremolo etc. reverb and compression as well. If you
have any ideas I'd love to hear them. Thanks, WP
