Happy New Decade - Re: Plugging and metaphors - ADSR.
I have has noticed overall - (and of course this is subjective), that plugging any opiate, pure (ie, morphine), synthetic (-codones, tramadol) or even compounded with other substances (APAP) for example, provide about 20-40% BA over oral. This personal statistic reflects onset-time, intensity but not time of experience. Estimating that time of experience is about 20% less than oral.
I'm an acoustician. In reverberation and synthesis, we use an acronym (ADSR) to describe the characteristics of an impulse and it's aftereffects.
Attack
How quickly the sound reaches full volume after the sound is activated (the key is pressed). For most mechanical instruments, this period is virtually instantaneous. However, for some popular synthesized voices that don't mimic real instruments, this parameter is slowed down. Slow attack is commonly part of sounds called pads. This is like IV vs. Oral with plugging somewhere in between
Decay
How quickly the sound drops to the sustain level after the initial peak.
You know this, BL users. Too bad it has to happen, but an orgasm is how God feels ALL the time, and we are not gods. We are junkies.
Sustain (the NOD)
The "constant" volume at which the sound remains following the decay until the note is released. Note that this parameter specifies a volume level, not a time period.
Release (The Come Down)
How quickly the sound fades when a note ends (the key is released). Often, this time is very short. An example where the release is longer might be a percussion instrument like a glockenspiel, or a piano with the sustain pedal pressed. Some time is is long, like the release of a bell struck.
