When multiple sounds are playing there will be pauses/total volume drop of one or both of the sounds. eg If “rain on tent” is playing alone, it’s fine. If paired with “thunder” (or anything else) there will be a silence/pause in the rain loop starting about 20 seconds in to playing and randomly happen after. I gave up trying to time it. Sometimes both sounds will drop off resulting in complete silence. Bummer because otherwise this was exactly what I was looking to buy.
I love this app, particularly the sleep sounds, I fall asleep a lot faster.
