As I see, the unipolar vacuum collapse theory only makes sense, if there is a chemical reaction that removes CO2, H2O, O2 or N2 from the atmosphere, (and one assumes no matter is transformed to energy) - well NO2 and O3 are produced, but that doesn't account for the volume.
Really? I'm not so sure about that.

I'd love to believe that sound can turn matter into energy, it would really cheer up my day. But I think esoteric explanations of sonoluminesence are quite unnecessary, This looks like plain old "pumping" to me. The smoking gun is the colour...blue-green which is the 337nm emission of nitrogen... which is in air.
337nm is invisible ultraviolet. See the spectrum here, it is multicoloured: http://astro.u-strasbg.fr/~koppen/discharge/nitrogen.html Here's one of air: http://www.scitechantiques.com/MMs_project/reference%20paper/Air_Spectrm_5mm... It seems to depend on the amount of water in the air what colour you get, the hydrogen makes it more red.
So it's electronic in nature. No need for mini-black hole theories, the energy comes from the sound and somehow (probably by dipole movement) becomes electromagnetic, excites the nitrogen shell and is re-emitted as a 337nm quanta.
The sound is a result of the expansion of the ionized air in the channel that was suddenly heated by the passage of huge numbers of electrons.
