[PD] Re: readsf~ / soundfiler crash with lots of big files

[Stefan Turner]

Cheers for the reply. At the moment I've actually got
it using readsf~, but I tried soundfiler which crashes
too, even using all relevant flags.

25 7-sec stereo wavs is quite impressive, but only
about half as much RAM as 12 ~30-sec stereo wavs
(which I'm trying). Even though I'm only _storing_ the
very first bit of each file, I can only assume that
both readsf~ and soundfiler (try to) grab enough
memory for the whole file. If you still had that patch
it could be interesting to see how far you could push
it. Sounds cool anyway if you fancy redoing it :)

I'm using PD 0.37.1 devel from PlanetCCRMA. To be
honest I don't know if soundfiler is threaded in that
version, but afaik readsf~ always has been, and
doesn't work either. I am using -rt (kind of
obligatory really) but the watchdog gives it quite a
while before killing it.

I guess the only solution is making copies of the
first 4096 samples of each file and loading them
instead. Just thought maybe there would be an easier
neater way.
