Some handheld recorders, for example, allow for saving "markers" in the file. This is not inbetween the samples, obviously; these are saved in the header. A typical application of that is e.g. a journalist marking "next question" or a field recording marking "next song". I have a ZOOM H1 recorder and a Microtrack II recorder which do that. I believe SoX does preserve that information in the audio header, but it's been a long time I checked so I am not sure. What Mark has seem to be sampled trumpet notes, so I don't know what kind of markers would that use and why, but let's see what he reports.
