The other day I found an old Olympus VN-480PC Digital Voice Recorder and thought that it could be useful. The first thing I did was put some new batteries in it and connect it to my desktop (running Ubuntu 12.4). Nothing…! A quick Google and I found this page and installed the software from the odvr project located here and all was well. Here are the steps that I took:
You can get a few other commands by typing in sudo odvr -h.
Usage: odvr [options]
-= Options =-
-h : This help.
-v : Print version.
-d <folder> : Download all files in <folder>.
-e : Download everything.
-l : List all files.
-x <folder> : Delete all recordings in <folder>.
-c : Delete all recordings.
-y : “yes” to all yes/no questions.
-r : Reset the DVR. This may fix some sync issues.
-D : Enable debug tracing.
