I would like to get a speedup version too! Maybe Dick could provide too versions of the podcast.

with kind regards,

It sounds pretty good to me. It could be faster but speeding it up
much more would require a lot of focus to pick up everything. Shaves
the time from 1h 27 to 1h 13 - so that's a full 15 minutes saved.
Unfortunately the size of the podcast doesn't change much (mostly
because due to the speedup, you need more bitrate) - just 1 MB saved
off of the 61MB of the original.

It did take my older home server a full hour to decode the mp3, tempo
it, and recode it. I also still need to figure out a way to re-add all
the id3 stuff into the final result. Right now its just a blank mp3
file, no notes, no picture, no name.

Anyone got some bandwidth left over? I can script automatic uploads +
run the RSS feed, as long as someone else hosts the files.

Could be a solution for Dick's repeated failed attempts to put the
posse episodes on a diet. I like em fullsize, so perhaps this is a
good enough reason not to cut into the discussions.
