You can play with it a bit but something like 2048 or 4096 is probably a good starting point. (Lower than that will likely provide incremental performance gain; you can go as high as you want up until you start getting crackling again.) As long as you dont try to access the whole file immediately (e.g. for normalization or other offline processing) it should do the trick for your use case. There may be other limitations but Im not able to recall them off the top of my head. </div><div><br></div><div>Btw, me.yield doesn't allow for sound to process, for that you would actually want to pass time in between the audio file loads, at least one buffer size's worth of samples. me.yield is chiefly a way to tell the shreduler to run other shreds without a progression of audio time. </div><div><br></div><div>Spencer</div><div><br><br></div></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 2, 2020 at 2:20 PM mike clemow <<a href="mailto:michaelclemow@gmail.com">michaelclemow@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hey Michael!

Also, because I'm triggering these "cues" from across a network, I'm trying to trade "immediate and real time" for "reliable and low-memory impact." I've definitely built applications like that with Chuck that ate all the memory before!
