What are we meant to look for on that Wikipedia article page, and how does it relate to looping? The article says nothing about cue points as far as I can see.
Looping (with normal WAV files etc) is gapless playback. You can get almost perfect looping if you use buffering.
The wikipedia article is basically just illustrating that, to do looping on an iPod (as requested) you would just require sample accurate wav files, and a media player that supported gapless playback.
My apologies but what I was wondering about was rather, even though that article tells us which players support gapless playback, it doesn't say which players support loop points.
In order to know which player to use we would need to know which players support both gapless playback and loop points. Preferably the list of such software would also state whether the player was also able to do gapless playback of loop points, since conceivably a player might be able to gapless playback when transitioning between songs but might not do it properly in the case of loop points.
