Hello,
Just wanted to toss in a new effect I've made with ftconv and Cabbage.
It is called Liveconvolver and can live sample an impulse response and
start convolving before the recording of the IR has finished. During
recording it creates overlapping instances of ftconv using what it has
captured of the IR so far. The effect was made as part of a larger
research project on crossadaptive processing, where also several of
our friends here takes part.

More info here:

There is potential for optimization of the process, we'll get to that next.

Wow! That's awesome :D

Thanks for the detailed description of it too, very interesting stuff :D

Hi,
Yes, I am recording the piano as IR and triggering it (convolving it)
with the sound from my voice. What is really unique is that it starts
convolving even before the IR has finished recording.
I've set a maximum length of the IR recording (5.9 secs at 44.1kHz),
but that is just an arbitrary limit, we could record much longer just
by using a larger table size. For each new recording, the IR length is
just the duration of the recording, independent of the max duration.
Glad you like it :-)
