How you have the audio levels set for recording is perfection. Some people go way too harsh on the gain or treble. This feels like classic asmr from like 10 years ago.
I personally wish you'd find another source of the tongue clicking. I can't deal with ANY mouth sounds. This was at my highest tolerable level. Whispering to me is actually the worst type of ASMR. I for real don't get why people don't try to smash the crap out of their phone or computer. Well yeah I understand everyone likes different things but if you every want to torture me for information Just put on an ASMR whispering video on loop. I only have it when it's enhanced through a mic so a whispering in my face wouldn't work lol.
