dear list,
i´m trying StereoConvolution2L for HRTF with the a sine tone for
testing.
As soon as I start a new kernel (with another impulse response
buffer) a click occurs...
Is there anything I have to take care of / preparing the buffers in
a special way to avoid these clicks ?
sine tones are the worst test material for this, as you will always get
artefacts, even when interpolating.
I see...
which version of SC are you using (last change to this UGen was 14th of
February) and what code are you using? please post!
i did a svn update and recompile today...
basically the clicks are not noticable with other sample material.
so if you think that this is a basic problem...
thanks for help :)
cheers, sven
