I was wondering if anyone had any good ideas on how to construct a power for generating sound (for example music) over an area. The "standard" method, used in the Power Profiles book, uses the Illusion power, but that has some significant issues- first and foremost, it is an illusion, not ACTUAL sound, and by the rules Illusions can have no real world effect (thus cannot be recorded, for example). It can also be recognized as illusory. I'm looking for a way to produce actual sound- probably as part of an array or package with other sonic powers (another reason to avoid Illusion- why should a "personal rock concert" effect be any less real than a sonic scream?).
One way would be to use the Illusion power mechanics, but a Feature that it is actual sound- this seems kind of lacking.
Another way, hinted at in another of the Sonic power entries in Power Profiles, would be to use a variation of the Environment power for light/illumination, but to say that it affects hearing instead of sight. Power Profiles uses the 'reduce visibility' effect at -2/-5 to represent noise dampening- but you could use the 'lighting' effect instead, with dim/full illumination mapping to quiet/loud noise- using the Selective and Precise modifiers to vary the sound level in the area, and generate specific noise (notes of music, for example).
Does anyone have any other ideas of how to handle this, or any ideas to make either of these options work better?
