Hi All,
I am currently completing my BSc in Audio Production and am wondering
if anyone knows how to use the convolve object in pd-extended?
The halp page doesn't show any info at all, I would really like to map
my own convolutions using pd but have not got the knowledge on the
object.
Any Help Appreciated
cheers
Graham
did you contact the author?

There is no [convolve] object. Did you mean :
[pix_convolve] [pdp_conv] [#convolve] [tab_conv] [mtx_conv] [convolve~]
Ok, you said audio, not video, but even then, several of them are useful for audio. I mostly just wanted to bring your attention to other possibilities, and to possible ambiguities that arise when asking questions.

how about using fft~ and friends to do the convolution. after all, it's a BSc in Audio Production :-)

he means [convolve~] which is part of Pd extended, from the mjlib. At least I have it here under OS X. It has no help file indeed.

I just looked at the source, and it doesn't do any multiplying in the frequency domain. It seems to route the input signal alternately to either the left or right outlet.

It's worse than that : [convolve~] does strictly nothing at all. It doesn't do what it says in its comments.
convolve_tilde_perform doesn't even write to its left outlet and right outlet buffers, and it doesn't read from its inlet buffer.
To make an audio convolution, you can use several [z~] with several [*~], or whatever is equivalent. There exist some shortcuts : for example, [z~ 1] multiplied by anything and added to the original signal, is something you can do with [rzero~].
In longer-term cases (big delays), it may be better to use [delwrite~], especially because you can share a single queue for several different delays at once, and because you have the option of using [vd~] for more precision, smoothing, and clickless change of delay.
Certain useful patterns of infinite convolution can be made by using delay lines with feedback (and a small enough [*~]).

If you want to do impulse response based partitioned convolution (usually what engineers/producers mean by 'convolution'), try the partconv~ object. It works pretty well with any .wav impulses (although not the Altiverb ones).
