Dear José Thanks for the hint. I was indeed aware of this library and would also use it if I'd hit a memory limit and would be dealing with sound files. It seems like purpose is to allow to store specifically sound more efficiently, no so much arbitrary byte-level data (though one could easily wr

Roman, maybe you could use iem16? https://git.iem.at/pd/iem16 says that it is "16bit storage for Pd" looking at the helpfile of [table16] we read: "[table16] stores 16bit values. The normal pd-tables ([table], array) store the values as floating-points. While floating points are (often) more pre

I read once in IRC that one value in a Pd-array requires not 4 bytes, but 8 bytes on 64-bit systems. Yes. Pd's graphical arrays (and Pd's data structure arrays in general) are implemented as a linear array of "words" (t_word). A "word" can hold one of several possible types. It is implemented as

Hi Sometimes I stored byte data (lists of bytes) in arrays. IIRC, I read once in IRC that one value in a Pd-array requires not 4 bytes, but 8 bytes on 64-bit systems. Since storing plain bytes seems not such an uncommon use case for me, I wonder if it can be done more efficiently. Not that I ever
