About memory and delay/sampling time

Hello everyone,

I’d like to know how many milliseconds per channel are the maximum reachable for delay/sampling, and what is the best strategy to avoid memory overflow.


The OWL has 1 Megabyte external memory available for audio buffers, plus some of the microcontroller’s internal memory. 1Mb at 48kHz sampling rate, with 32 bit samples, is 10241024/(480004) = 5.46 seconds total. So you should be able to do at least 2700mS per channel stereo delay, maybe a bit more or a bit less depending on what other memory hungry objects you use.

Thanks a lot for the reply, I’ll try.
