So you would not be requiring a uncompressed file to accompany the mp3 
or whatever? You seem to be expecting a upload of a uncompressed file to 
then be generated into a mp3 by your archive.

It's not file type, it's file size we are discussing.

Of course, though you loose control of it. I prefer to generate my own 
mp3s for people to listen to, I know what the original site sounded like.

They have been ignored by the group for some time. The group is split 
with many unable to participate because of the huge file sizes involved.

Some of the files that have been put up in this group would take me much 
more than overnight to download. And upload runs at a slower speed than 
download.

I am getting around some of the problems by taking the MacBook out and 
pirating high speed wireless connections. Not so much for sounds, but 
most software updates are now downloads, and they can be very big. Not 
everyone has that option, however.

It's in transition. I've not yet moved my website to MPEG4. But I expect 
to do so in the next few years. I was pointing out that a long term 
archive needs to be updated from time to time.

I got caught out by heavy afternoon thunderstorms on my trike that built 
up right across my route while I was out. Spent a hour on the porch of a 
abandoned house waiting it out. That was after managing to stay ahead of 
it for 15 miles. Then in a break in the rain and lightning went another 
mile down the road to a country store and sat under their awning with 
several farmers discussing weather, how they had been rained out of the 
fields by the storm, bike touring, etc. Anyway, only did 25 miles of a 
planned 50+ mile trip.

Good way to see and hear birds out on the trike. And inventory roadkill.

Our feeders are not being attended by Pine Warblers like they were all 
winter. Most must have migrated. Instead it's Goldfinches and Blue 
Grosbeaks, plus the usual Cardinals, assorted sparrows, chickadees, etc. 
And last night the frogs were busy filling our water garden spots with 
eggs. We are way, way behind on rain.
