What's faster as a workaround is to call snd-xform with block size equal to step size and again for snd-xforms of the sound that remove a multiple of step-size samples. Then use snd-fromobject to interleave the samples of the several snd-avgs.

That fixes the trouble... sometimes.

Trying another workaround. Compute a convolution with a big window as a sum of convolutions with pieces of the window, shifting the summands appropriately. Should give identical results, but avoiding large windows if I use sufficient pieces.

It seems after all that large convolution windows are the source of the trouble, though only when snd-avg is applied, but then even if the convolution has been the input to sum, snd-xform, or snd-flatten.
