I just downloaded the 01.01.18A firmware update for my 2GB Clip. The voice recorder works leaps and bounds better now. The old firmware (and my m200 players) recorded some kind of low bit rate file with the voice recorder. The new Clip firmware records 16 bit 24k sampled uncompressed wav files (Windows PCM). The audio quality is very good now. The files are larger, about 3MB per minute, but the improvement in sound quality is worth it.
I work in radio. This amazing little device would make a decent field recorder for news. The audio quality is good enough to use on the air. The sound quality is amazing when you consider the size of this thing and the tiny microphone behind the equally tiny hole in the plastic case. Check it out!
