It took many years to track down the compound but I finally acquired it in the spring of '21.
It caused increases in timbral perception and aural acuity. I could hear marching drums coming from the city center, From across the lough I could pick out their faint rhythms.
At times things sound as if they've been shifted a 5th down or have reverberant/echoic tails on them.
My housemate found it hard to understand me when I neglected to pronounce my consonants because I was not paying attention to the higher frequencies. Despite this the cognitive effects are gentle and unobtrusive (which is relieving as tryptamines can produce confusion, in concert with their enhancement and suppression cycles).
Music is listenable at this dose, and sense of rhythm intact; Would that be the case at higher doses?
During the offset my ears felt warm, Waves of spontaneous physical sensation washed over them. This tingling feeling reoccurred a couple times over the next day, albeit faintly.
Interesting that there would be an aural psychedelic. Intriguing that other base tryptamines should be inclined towards other sensory modalities.
DiPT for sound, MET for vision, MiPT for touch; What sense DMT, DET, and DPT affect is unclear. As is, the known psychedelics have a broad range of effects. The particular specializations of the xxTs are most curious.
Ingested 30mg of diisopropyltryptamine on 30/07/2021 at 21:37. Excellent experience, necessitates further inquiry; high priority.
According to other reports DiPT breaks our musical scales in a rather odd way. What might this say about the relationship between music and mind, and can psychedelic geometry can tell us anything about the topology of mind? I wonder would it be possible to replicate DiPT's aural effect using audio software. The rather sparse literature speculates that "[t]he subjective decrease in frequency of sounds is a fixed value which leads to... jarring distortion of harmonic intervals" (Shulgin, Alexander T. in "DiPT: The Distortion of Music" 27). This should be possible to model into an audio processing FX unit.
Not "everybody needs a 303" but every audio engineer should consider taking DiPT.
