[PD] most efficient use of [partconv~]

[Roman Haefeli]

hi again

i made a patch, that uses several instances of an abstraction based on
the partconv~ external in order to do binaural spatialization of sounds
using a set of hrtf tables.  the hrtf files are all loaded on loadbang
into tables, so that they can be accessed quickly. it is part of the
patch, that a 'set <tablename>' message to all [partconv~]s is sent
quite often, which leads to dropouts on the box, where the installation
is meant to run (for some reason not on my personal laptop). i also
noticed a difference in performance between an old version of partconv~
(0.1) and the current svn version, whereas the latter is more likely to
cause dropout at high 'set' message rates. 

there are some things, that i don't know, which might affect
performance. for instance, what is the recommended blocksize of the
subpatch, that contains an object [partconv~]? is the optimal blocksize
dependent on the size of the impulse response? is using [partconv~]
generally not the best option to implement hrtf? if so, what are better
ways?

thanks in advance for any help.
