Just to add an update to this: I was able to improve the "seam" in my seamless loop by manually setting the loop start to the priming frame count from afinfo, and the loop end to priming + valid.
However, I'm now wondering whether a truly seamless loop is actually possible with compressed audio. Since the signal at any given point is always an approximation when encoded, the audio on both sides of a "cut" in the original wav must also be an approximation, meaning that the two sides won't necessarily be as "similar" as in the original. That seems reasonable to me, but is it correct?
I'm talking about a "seamless" loop of an ambient soundscape recording, btw, so there's no actual silence (i.e., it's not a drum loop or anything like that).
