I'm looking at an interesting problem at present that I lack the expertise to do much more than wonder about. The basic problem is this: How might I quickly, cheaply, and effectively take a snapshot of an acoustic space [mono is all that's required here] and then convert that information into a map of energy distributed across the audio spectra? The eventual endpoint of such a transfer would be to map that information as MIDI data [I know, it seems like a hack, but there are already a lot of pieces of gear out there [faders, outboard signal processors, mixing boards, lighting, instruments] that *already* take MIDI stuff. We're talking the second time in as many weeks that people have asked me about doing this, and neither group has anything that could be considered as resources.] and then route it to various kinds of things for control. Some kind of Fourier thing would sure handle this, but I'm also wondering if there isn't either something already out there OR some kind of "equalizer on a chip" thing that could be pressed into service for such a task. What better place to inquire on such a thing than among the solons of DSP? In the interests of bandwidth, this should move to mail. Just think, your advice could be the bit that alters forever the face of a production of Shakespeare's "The Tempest"! Thanks for your patience and advice. -- What is poetry?:The medieval frieze, with frieze/Of Boy Scouts from Nagoya? The snow/That came when we wanted it to snow?/Beautiful images?
