A bit of technical production data on the recording of this story (possibly misplaced, so mods, feel free to move if necessary) ...
I've seen several posters on the forums asking for some better way to audially indicate scene breaks within a story. In this recording I experimented with inserting 2-3 seconds of pure (not recorded) silence between scenes. I also carefully trimmed out any breath sounds before the start of a scene. While the difference is subtle, I feel like this marks the start of a scene very clearly, and it seems like a pretty effective way to distinguish between scenes without having to insert a tone or something else that might be distracting.
That's generally what I do when editing Pseudopod, except I use "ambient silence" from somewhere else in the narrator's recording. The reason is that even with a good, clean recording, the ear can sometimes detect the difference between "pure" (i.e. generated) silence and ambient silence and it can be slightly off-putting. Leastaways that's what I've been told.
(Actually it's part of the ACX guidelines as well)
I aim for 3-4 seconds silence. Not everyone likes that
