I like to use voice recorders for my lecture, and some of my classmates use their iphone for theirs with very good quality. My experience so far with these voice recorder applications have been pretty bad: the apps either record poorly or force close before the lecture ends. So far I have tried VoiceRecorder and Rehearsal Assistant. VoiceRecorder is unstable and records poorly. Rehearsal assistant is capable of producing high quality recordings (that run in the 300mb range for a 90 minute lecture), although it occasionally force closes. Anybody have any recommendations for a decent voice recorder that uses a reasonably high-quality compressed format (preferably not 3gp)? Thanks!
