Task #1 I want/must/should/can take away is the XMMS plugin.
An important second task is maintaining of test samples.

All lossy encoders take benfits from such a web page.
AAC, AC3, Lame, Musepack, Ogg Vorbis, MP2, dts, ...

Currently there is a very old test sample page for gpsycho:

http://www.mp3dev.org/mp3/gpsycho/quality.html

I think such a page is very important. Otherwise developers must
waste time to hunt for test samples in web forums which appears
and disappears very quickly. Most of the test samples you can't download
2 or 3 days later.

This is a mess and annoying (at least for such persons like Frank Klemm).

The other problem is, when you are downloading these samples,
then you have the mess on your hard disks. Thousands of files
with names like goldc.pac, Hex.pac, jo3.ape, dr4.pac, t1.pac, track07.pac,
lalaw.pac, 11.wav, lust.pac, hvmh3.shn, beo.pac .
You don't know the source of these files and you don't know anymore
what encoder problems these files show.

I have 2,5 GB (4 full CDs) with files with such names. I downloaded
they sometimes somewhere for an unknown purpose, but after 6 or 12 or
24 month I don't know much about these files.

I can backup these 4 CDs and give it CHJW, because I can't upload 2,5 GB
of data.

This job must be done by someone with useful ears (he/she must make
some checks to avoid too much SPAM in this list), a wide band
internet access, a lot of web space and he/she should be able to send
the test samples on request via S-mail (5..10 €)

ok. Since I really want to use the HA wiki for something useful I stole most of the idea from Ganymed and made a wiki page:

http://doc.hydrogenaudio.org/wikis/hydrogenaudio/TestSamples

What do you think?
