a sampler chunk for wav files?
eh… guess not 
can’t say I’ve thought about it - you mean like a rex file type of thing?
like this: http://www.sonicspot.com/guide/wavefiles.html#smpl
that way you can add loop points to files when exporting.
good website - thanks, I’ll bookmark that.
It’s easy to add chunks like that to the WaveAudioFormat class - the hard bit is playing it back!
well the only time you would need to worry about loop points for playback is if your playing it back from a sampler.
