orry- was being lazy. Next time i post a playlist (which will be after i've
bought a new HD & crammed as many q5 oggs into it as possible) i'll stick in
plain text or stick an url in the body of a email.

about 3hours just for my albums, but i was doing other stuff at the time.
When I did a rough estimation of time, it took me 10 hours to do the
collection & tag it properlly @q10, since i wasn't using the on the fly
encoding method, and i had to do housework & college work at the same time.

My definition of lots is getting my collection back to its
approaching-90-hour length. It was originally around about 88 hours, but
since i started using Vorbis, i got so sick of the poor quality of MP3 i
just deleted all my illegally downloaded mp3s in 1 (well, a few) fell swoop.
Bet that says something for open source audio compression. (very little
questionable media is left on on my computer- only those that are hard to
find such as the english vocal version of VOICES by Yoko Kanno).

Yes i did (admitedly, i forgot & attatched it in another email)

The one in the college theatre is okay (but the theatre is not the most
acoustically sound in the world), and considering the middle end PA system
is mostly to be used in the middle of a field at Houghall, i doubt there'll
be any people with good enough ears who will actually care about any minute
loss of quality.

My albums are now encoded at q6, my sisters cds & my singles are encoded at
q10.
Suprising how lowering the quality by just 4 points can leave me with about
1.65GB free.

2 things:
1) why
2) i checked the archives, (apart from the fact the rehuff.exe apparently
doesnt exist, or getright needs its ass kicking), and it said the current
version of the rehuff tool breaks seeking in all current players. so i guess
i wouldnt use it to squezze 22MB of free space from the collection (which
would amount to roughly 1 single)

Testing on "Yoko Kanno - Macross Plus Original Soundtrack ~ for fans only -
13 - VOICES (a cappella version)" at different combinations ranging from
default speexdrop config to q10 complexity 10 resulted in good quality
compared to 16KHz wave file (which on my system was basically
indistinguishable from the cd as it is just pure vocal). Which is why i
posted a thing titled "sticking a speex file inside a vorbis file"
