After three years of using Muse, I’m 99% certain that’s correct. Interaxon employees rarely respond to posts in the Using Muse forum, but you can probably get confirmation by sending a private message to Interaxon’s customer support. FWIW, I don’t think customer support has ever failed to respond to any of my inquiries.
I don’t know, but I have a suggestion: try using the “City Park” soundscape instead of whatever soundscape you’re currently using.
Version 5 of the Android app (released seven months ago) introduced a bug where the birds would unexpectedly stop playing while a user is in the “calm” state. This bug hasn’t been fixed in the current version of the app (v. 6),
The bug is a problem because it makes it difficult to detect when you’ve drifted from “calm” to “neutral”. Fortunately, the City Park soundscape contains an audio cue that’s not available in the other soundscapes: when you’re in a neutral state, this soundscape plays human voices – they’re indistinct (the language sounds like it might be Asian), but they’re clearly audible. And when you’re in a calm state, the human voices go away. This makes it easy to tell which state you’re in.
That’s a notification that @linky7 liked one of your posts.
