I see. Happens to me too that I lose focus while listening to an audio recording. But not to the extent you describe. Have always had difficulty separating voices from background noise though, like when a few people talk in parallel or when loud music is playing in the background. I don’t remember what that’s called, but I remember a long time ago reading that it’s a thing. Doesn’t affect my gaming much though if at all. Anyway I’m always interested in things having to do with auditory perception, thanks for sharing.
