On the contrary, this is not sample perfect: a line in my crontab, starting a recording of one minute every minute. * * * * * /Users/hans/bin/rec -q /tmp/file-`date +\%s`.wav trim 0 00:01:00 This does indeed record each minute of audio into an appropriately named file, but the transition is not seamless (as verified by playing a song longer than one minute). But if you change this to record your "predefined blocks" of a couple of hours, then perhaps overlaping a few samples will not matter if the seams are at silent times. Or you could record whole days, restarting at, say, 3 am.
