#21 slow on large files

[markus kantola]

Rezound is quite fast with regular-size audiofiles but
I have to work with 90+ minute long files and then
Rezound is getting slow. How can I reserve more memory
to Rez? Is it designed to handle files this large?
I'm testing it on 64bit AMD 3000+ with 1Gb DDR, FC3-64bit.
Does it need a finnish translation? I'm willing to
translate if it's needed.

Software necessarily get's slower as data gets larger. It
also necessarily takes at least longer in a linear fashion
because it has to iterate over the data in a linear fashion
when doing anything to it.

However, that's not to say that rezound could not be
optimized a bit more. This is something I want to look at
after more of the funtionality is in place.

One thing you could do to speed things up is making the
internal sample format 16bit integers instead of 32bit
floats. I'm not sure how you'd feel about that.. some work
requires floating point accurate calculations, but you may
not. If you want to change it or experiement with the
results, you can configure rezound with the
'--enable-internal-sample-type=int16' This cuts the working
file size in half and doesn't require floating point math
for everything.. (which I'm not sure how the 64bit AMD handles)

I also routinely deal with 90 minute files. I agree it
takes a bit of time and I have not yet compared it with
other software to see how it measures up. What I used to do
was do an action and come back in 10 minutes to do the next
thing. However, now I'm implemented macro recording so that
I can do a bunch of actions (that I repeat regularly) in one
step and walk away for a long time and come back. This is
in CVS, but not yet in a release. There are some other
things I need to do before the next release, like find this
nasty lock-up bug.. (which may be a glibc, X11 or FOX issue
actually)
