Hangups always happen in the smallest details. It took no
time at all to build an entire new psychoacoustic engine
from scratch (once I managed to track down the appropriate
research papers), but something simple like mapping the new
log scales onto the existing codebook abstraction turns out
to suck time because I hadn't stopped to think about it long
(How do you add a number to -Inf? You don't; you find a
to avoid doing so. There went wednesday night through
The hard part is never getting something to work. The
part is building an abstraction you won't be ashamed of two
weeks later.... especially vital in the case where the
abstraction could well last 20 years. Bad way to lose alot
of time when chasing an unreasonable deadline....
Anyway, the major hangups are past I hope; decode is
certainly clean and I can live with well documented hacks
that are encoder only. Integration of the New Stuff (tm)
with libvorbis is first-pass coding complete, but totally
untested. I'll do that after sleep. After making sure it
works, time to build codebooks--- after adding log
quantization code to the trainer. Gaah.
At least the end rush will just be for the website.
