If you know in advance what set of files to choose from, you could start by reading in a text file with all the file paths then make the random selection in chuck. This avoids system calls, which can mess with the timing of your real-time application since the chuck VM misses the time spent doing the system call (i.e. Std.system(“sleep 1”) causes mayhem). But if you want to be able to add files to a directory on the fly I think you have to do the system call. Just be aware of the timing issue - maybe it can be done in a thread. -Julian

Hi

I'm trying to write a function that reads a random samples from a directory into a SndBuf. I'm not aware of the the necessary functionality being available in chuck, so I wrote a bash script that picks a random file from a directory and writes the name with full path to /tmp/random_file. When I call Std.system() I get a warning that I should use --caution-to-the-wind. This works well in chuck, but in fact I'm in miniAudicle, how do I call miniAudicle with that option? Just doing

$ miniAudicle --caution-to-the-wind

makes miniAudicle think I want to start with a blank file called "--caution-to-the-wind"...

Nevermind, I'm back to chuck, seems much more stable...
