How do I stream sound to disk for long recording?
Jan 6th, 2010, 9:23am  
Hi,

I'm trying to record my lecture with minim and I found that minim can't record long recordings. I'm trying to record 5-10min at a time for each slide I'm going to explain or formulas I write on the board. I found an old post about the same problem and the author of the minim suggested stream audio to disk but the post thread didn't really discuss how to stream audio to disk. The recordLineIn example is buffered (unknown amount of buffer). How do I start from that example to stream audio to disk so I don't have to worry about memory running out? Thank you!

I'll just answer this myself in case someone else is also looking for this obvious answer:
 recorder = minim.createRecorder(in, "a.wav", false);
the false disables buffering in memory so sound is streamed to hard drive as is is recorded. I wonder why such an obvious thing is not clearly mentioned in the document.
Here's the document: "buffered - whether or not to use buffered recording "
