But for SIMD to be fun, data should be interleaved...Yes and no.While interleaved channels would certainly help with "channel-wise" vectorization, it would make things *worse* for multi-channel "block-wise" vectorization. IMO, any object that can do block-wise vectorization would likely do so with

Sorry forget it, "frames" actually corresponds with the comment

Howdy Miller,
Multi-channel will be very useful, especially in the context of some of the
sound spatialization work we have used libpd for at ZKM. A good idea from
Ableton/Max which we can profit from as well. :)
I agree with the naming suggestion from IOhannes.
The CoreAudio API also uses

I'm not sure about that: in many APIs the word "frame" means one
"multi-channel sample", e.g 2 samples for a stereo stream.

Actually, after Winfried Ritsch told me about the "pd_snake" project, I
came up with a couple of ideas on my own. You can find them here:
Hi Pd dev -
I'm preparing to rework the DSP network to give tilde objects more control over
their inputs and outputs, for instance allowing for multi-channel signals and to
allow objects to decide for themselves whether to promote float inputs to
signals (so that you don't have to say "+~ 0 to
