[PD] Get room impulse response

Mon Oct 27 02:19:36 CET 2014

Slightly off-topic but there was mention of a proposal for porting
HISSTools to Pd but it's a big job and there wasn't any momentum - this was
a couple of years ago now.

Spoke to Harker a couple of weeks ago and this topic came up again.  The
(BSD) code's in good shape and he's parsed out much of the Max/dsp code to
aid a port.

It's all still outside of my skills/time (and isn't that the general
problem) but it would still be a worthhile additional lib to Pd, perhaps
even just a few objects such as the convolution that's all over Live (for
example) these days.

Just saying like.

Anyhow, good luck with it Jack, IR's are a fun topic.

REgards,

Julian
