[PD] better tabread4~

well, tabread4c~ is far from perfect, it has the same aliasing problem than tabread4~ and
it create more distortion than tabread4~. (but in lower frequency).
one told me that modern commercial audio software can use 32 points shannon interpolation.
i'd like to try that...
it will be more expensive, but this is negligible on recent hardware, and sound quality worth it.
so, for now, i'll try different interpolation schematic, and we will see latter what to use...
