1) the question is now how to fit a single set of N

memory. Its how to fit *all* the samples to be processed in a given

isn't conducive to this.
If 96 frames are enough for stability (and say 64 isn't), then sample 96
- 127 in a 128 frame buffer are a waste of memory anyway and only adds
to latency.
It may even be so that a set of shorter buffers that are only partially
aligned - but allocated as one continous area - may have a greater
chance of fitting into available cache, without trashing other important
data.
