Sorry for my own. And as you are the only one who has so far reported this, I'm afraid I'm stumped. It's possible it's machine-specific, only happens with certain audio files, or a number of other things; I'm afraid I don't have enough information. I might be able to look into it if I had a demo that was known to reproduce the issue, but that's kind of a difficult thing to work out over an itch.io chat (and even then, it would have to be able to repro on my own machine.)
