I have a number of recordings using a tetramic and Tascam DR-680, the recordings are mostly: church choirs among other recordings a full church with only singers making a 700+ choir singing Händel, Jazz recordings ( Benny Goodman style) in a club with audience eating and talking, One Gospel recording with all of the public joining in, A few short recordings of rainy afternoons with a bit of thunderstorms from the Swedish archipelago. A long recording of Early morning birdsong at sunrise 03:30, with absolutely no wind or man made background sounds, from a wooden glade in the archipelago.
Most of them can be distributed within this group and the ambisonic community if someone is interested and wants to listen.

I am now fully convinced that using the DEMAND library would be next to useless and not worth the work involved in trying to make it (partially) usable. Pity really, as a database of everyday noise would be a useful resource - but only if it's done properly in the first place. I am in the process of doing my own field recordings using a Brahma mic (been impressed with results so far: birdsong; a very noisy, reverberant restaurant; organ playing in a church) but as it will take some time to build up a complete library I was looking for some other material I could use, particularly every day environments. Thanks, Richard, for your suggestion of ambisonia.com. I started there but was having trouble downloading the torrent files. (The internet access I have here (in a shared building) blocks torrent files so I need to download somewhere else then transfer.) Will continue to pursue this route. Thanks again, everyone.
