Got an idea - tell me if it's already do-able with existing technology, simply not practical, or if I should run go patent it before somebody takes the idea and runs with it. The idea is for a preamp, or at least a device that would be part of the preamp chain, that could listen and adjust EQ based on what it 'heard' in the room. A small wireless mic/transmitter unit could be placed at some appropriate spot in the room that would 'listen' to the sound of the bass and make EQ adjustments for room acoustics. The unit would know how far away it was from the amp by judging lag in sound or radio waves or something like that, and could make suggestions to move the listening station closer or further away if needed. I'm not sure exactly how a user would 'train' the system to produce a sound tailored exactly to their taste (possibly adjustable presets like the Bass Pod or other amp modeller???), but assuming that problem could be addressed, the unit could help the bass sound consistent regardless of venue - it could possibly even work to balance against a soundman's questionable EQ in the FOH mix, under the right circumstances where there's enough sound coming off stage to have an effect on FOH sound. I know that years ago a sound company my band at the time used employed a device that produced a reference tone series for calibrating EQ, so I would imagine the technology is available. My tech savvy is pretty weak on these issues, so I don't know where that type of technology is at these days... Anyway, how dumb is this idea? Given that I often hear pretty lousy bass sounds at big venues with expensive sound gear and L337 soundmen, it's either a hopeless battle or something waaaayyy overdue... Thoughts?
