Egbert, strictly FWIW.... I spent an hour or two a few years back looking into what patents had been filed with respect to the recording of digitized voice data on flash memory. As best as I could tell, e.Digital had the first such patent. I cannot say that this is an iron-clad fact, but I have yet to be informed otherwise. I wouldn't mind if others pursued the same line of inquiry at the patent office's searchable database, http://patft.uspto.gov/netahtml/search-adv.htm . (I used a combination of key words such as voice, digitized, flash, record OR recording, etc as a filtered inquiry into the contents of the patent abstract.) If EDIG does indeed have the first such patent, the possibilities are endless.
