minim, looong recordings, out of memory
Jan 8th, 2008, 9:48am  
hi,

one of my students is trying to set up an applet to be able to record really long chunks of audio (people telling stories, couple of minutes). we've got it working as for the recording part (it's signed) but are now running into memory problems. any ideas on how to set it up to record 5-10 minutes or ideally endlessly?

sidenote: i tried reading Runtime.getRuntime().freeMemory() and it reports enough to go on recording but still i get out-of-memory errors ..? is this happening outside of java / the vm?

thanks
F

If you're really sure you're not doing something that can obviously be used to reduce memory usage (reusing large amounts of objects, or such truck) then the VM parameter (in eclipse, go to run...) that most of us here use for our sketches (loading images can fill up the mem pretty fast):

Code:

-Xmx512M


Seriously. It's that easy!

You best bet would be to use a streaming audio recorder, rather than a buffered one. Then the audio will be written out to file as it is being recorded, rather than being stored all in memory and then written at the end.
