So, I recently conducted several interviews using the Voice Recorder software. Most of the time, it worked well, but there are two files that have turned into disasters. In each case, the file resulting from the recording session appears to be the proper length (about 30 minutes in one case, 10 minutes in the other), but both go silent early in the session (about a minute in for the longer piece, just over 2 minutes for the shorter). Further, the file sizes are much smaller than one would expect for a recording of the proper duration. Any ideas what happened and whether this is reparable? Running repair softwares of the 3gp files has so far proved useless, and I haven't been able to find any relevant info online. Thanks for any suggestions.
