The most recent double episode (872 & 873) had horrible volume variance. So much so that it I couldn't listen to them. I've heard stories narrated by Amy Kelly before and have not experienced this issue before by her.
Could it be a technical glitch? It sounds as if she is moving near and far from the mic but I doubt that she would be that active during a recording session. Maybe a problem with gain input or something...
I'm searching for a third-party tool that will normalize the volume and allow me to enjoy the story. I verified that it was not Spotify causing the issue as the web version does the same behavior.
