The fact that when the earliest recordings were made they had no intention or technology to play them back but now we can (at least to get a rough idea) leads to a fascinating idea: capture of a signal may be decoupled from its playback, which may be impossible with current technology. This, of course, brings to mind the 2011 experiment from UC Berkeley (http://gizmodo.com/5843117/scientists-reconstruct-video-clips-from-brain-activity http://gizmodo.com/5843117/scientists-reconstruct-video-clip...). We shouldn't worry about the horrible quality of the playback for these but focus on recording and preserving the brain activity.
