ultrasonic crackling/clicking but only when..

[Shin]

Oh My god! I forgot to make my device repeats all tracks of AM6. Seems that i just had 6 hours listening on that day (night including). What should i do guys.? It was an accident. It takes a lot times if start it all over again. I'm on the stage 1 and day 13.

Shin, are you saying that you simply played tracks 1 through 6 once a day each day? That's what this sounds like, since no single playthrough of track 1 is 6 hours. That's not the right way to do it. You use track 1 for 32 days on loop, then stage 2 for 32 days, then stage 3 for 32 days, then...

I use all tracks, 4 hours in day and 4 hours in the night. It's 8 Hours as required. I use them randomly, Ocean surf-trickling-ultrasonic-ocean surf (it is random) . Is that wrong ?
