I work with a university production group and we've been using little Edirol R-1 and now R-09 portable field recorders to record events/meetings that are mostly getting posted as podcasts. We've had a couple of recordings go bad now. It monitors fine while recording, but playback sounds like digital gibberish. Seems that there's no user error involved, but that it just does this periodically. Setups are simple...a few mics into a mixer, out to the mini input on the recorder.
I haven't really been able to reproduce the problem, though when the mini connector isn't plugged in all the way, it does give a similar result. But I don't think that was the issue since it monitored fine.
So, first if anyone has any insight into this problem, please inform. And secondly, is this kind of digital file corruption just as likely in a higher end field recorder, or would we get more consistent results from a more pro product? Our current solution is to have redundant recordings until we figure out the exact problem.
We could consider DAT solutions etc. as well, but the convenience of recording in our final output format is convenient.
