Did you just get audio distortions from DiPT, or did you find it a true full blown psychedelic (mind-expanding substance) like I did?
after lots of experimenting with this stuff here is what i've found to be true at various dose ranges for
ME. Not everyone i know had the same response (but a lot did too):
<40mg - pretty much just audio distortion. Tones shifted down, male voices sound like Andre The Giant, female voices mostly unaffected. Music noticeably different but still recognizable. I am able to socialize easily at a party and i seriously doubt anybody knew i was on some crazy chemical. (aside from those who took it with me of course). All in all a fun time, but mostly a novelty at this dose.
40-60mg - Tones in music not only shift down, but up at times. Sometimes both at the same time. Listening to even my own music on cd is like listening to it for the first time. Only when vocals come in can i recognize a song.
My own voice and others are completely alien. Most voices and other non-musical sounds have a digital-effect-sounding metallic tinge to them. Some minor visuals during the peak and a sense of spacial distortion and a small degree of confusion were also present. (not in a bad way)
70-100+mg - Comes on fast and hard (more so as the dosage increases). A strange and colorful aurora-like haze around everything. My sense of hearing is useless as a means of communication. The best way i can describe voices is that they sounded like the cantina scene from Star Wars. Alien noises coming out of my friends' mouths. Music is indistinguishable from voices and vice versa. Every sound blended together in a way i cannot put into words. I was never at a +4 on this substance but at 125mg i was at one of the highest +3's i have ever been.
It would seem that (for me at least) my brain decided just to say "screw it" with all the crazy signals my sense of hearing was trying to process. This seemed to allow me to get more lost in my own thoughts and inner workings of my mind. Sort of the same way someone in a sensory deprivation tank would.
I hope this is helpful to someone. I am really not all that great at putting my psychedelic experiences into words.
