.. except if Pd is compiled as a 64-bit exeutable, each individual sample takes 8 bytes, not 4.

Dear list,

I have a quick question: For a looper/ringbuffer patch I'm using a couple of hundred arrays with a size of something between 4-7 seconds (at 44.1k) each.

How can I calculate exactly how much RAM one buffer occupies, so that I'm not overloading my machine? Is it the same size of a wav file?

yes, an array use the same mem as a 32 bit mono wave file. (or a 16 bit stereo wave file, like in CD)

1 sample is 4 bytes, there is 44.1 samples/s, so a table use 176.3 Ko / second (about 600Mo/h).

Thanks Martin
