My first intuition on this would be to have your continuous a/d process pipe to some custom process (not sox), which simply takes a binary stream on stdin and creates a continuous series of data files on disk of equal length (e.g. 20 minutes worth of samples, or whatever seems like a good interval), using some reasonable template pattern for file names.
Then, there'd be a separate process (running continuously) that scans for new files at regular intervals, and runs sox on each new file, converting it from raw to whatever format you want as a final product.

Subject: Recording in chunks using sox
Hi all,
I want to record 24/7 transmission of FM radios using DVB-T dongles. I want to direct the input audio from some dongle to sox, eg. something like
rtl_fm -f 88.8M -d 0 -M wbfm | sox -r 32k -t s16 - -t ogg device_0.ogg
here am using the rtl_fm terminal program.
Can sox help me save the continuous FM audio that comes from rtl_fm to be saved in some time length chunks, say 10 minute long chunks?
It means that sox would write to disc every 10 minutes.
Thanks for any help!
