Right so this is something that's genuinely baffled me for years and I rarely see it discussed properly. I've had recordings where I'm absolutely certain I heard something faint in the room at the time, almost like a breath or a low hum, and then on playback through my Zoom H5 it comes back completely transformed, different pitch, different cadence, sometimes what sounds like actual syllables. It happened repeatedly during a session I ran in 2019 at a farmhouse near Sleaford.
My working theory is that whatever we're capturing isn't static. The interference patterns in the audio file itself might be interacting differently with playback hardware than with the original recording environment. Has anyone actually done a proper frequency analysis comparison between the captured moment and the playback? Because I think thats where the real answers are hiding and nobody bothers to do the technical legwork.
Anyone else seeing this consistently or am I the only one who's logged it properly?
