I hear this term thrown about occasionally. especially when speaking of layering drum hits.
What exectly is enveloping?
what does it d the sound?
Can it be used on other sounds rather than just drums..
let me know your thoughts please!

I think enveloping means like having an d,a,h,s,r but then for pitch in this case, to make it go up and down.

attack sustain decay release, the 4 basics of an envelope. usually this is based off of key strokes in synths. but it controls timber, pitch, cutoff freq in filters, and just about anything else you could tweak. generally it's used for volume at the least.
basicly it is used for everything, even nto synths, like if yuo pluck a guitar it will take a long time to decay, and have a very fast attack. and if you remove yuor fingers from the strings it will release teh note almost instantly.
drums have a fast attack and a quick decay with almost no sustain. pitch envelopes can be used on anything it would make the note rise up when the note started and teh decay would bring the pitch down. works with kicks and toms.
pretty mcuh all the 808 909 drum machines are just synths with fast ASDR to make the drum hits. mostly just an envelope to make the volume fade, and usually the cutoff to help add some variance to the timber. pitch can be used too but to much sounds cheese. again Disco tom-tom drums.

i edit the att,dec,sus and rel on the volume of all of my samples i use in music.
its a must do thing. especially the release imo. does wonders on all samples.
e.g.. tightening kicks and snares to make them sharper.

Envelopes
AMPLIFIER ENVELOPE - The amplifier section on a synthesizer may be labled as VCA (Voltage Controlled Amplifier) or DCA (Digitally Controlled Amplifier). An Amplifier uses an Envelope to control the overall loudness (or amplitude) of the sound over time. Envelopes are activated by pressing the keys on a keyboard.
ENVELOPE PARAMETERS - Nowadays, there are many variations of envelopes available. However, the most common envelope has 4 parameters: (1) Attack time, (2) Decay time, (3) Sustain level, and (4) Release time. This is usually called ADSR Envelope.
Apart from controlling the Amplifier, envelopes can also be used to control other sections of a synthesizer. But for now, let us just look at controlling the Amplifier.
Basically, an ASDR envelope only has 3 loudness (amplitude) levels; zero (off), full (the maximum) and the Sustain level.
- Attack time it the time taken from zero to full.
- Decay time is the time taken from full to Sustain level.
- Release time is the time taken from Sustain level to zero.
Let us look at what happens to an ADSR envelope when a key is pressed on the keyboard {Note - Before any key of pressed, the envelope is at zero and so there is no sound}.
* ATTACK - Immediately upon pressing a key, the envelope "opens" from zero to full. This is controlled by Attack time. An Attack time of zero means the envelope goes from zero to full instantly (ie sharp attack). Increasing the Attack time means that this will happen more slowly.
* DECAY - While the key is still pressed, the envelope then drops from full to the Sustain level. This is controlled by Decay time. A Decay time of zero means the envelope goes from full to sustain instantly. Increasing the Decay time means that this will happen more slowly.
* SUSTAIN - While the key is still being pressed, the continuing envelope just remains at the Sustain level. This is set by Sustain level.
* RELEASE - When the key is released, the envelope then drops from the Sustain level to zero. This is controlled by Release time. A Release time of zero means that this will happen instantly. Increasing the Release time means that this will happen more slowly.
ASDR EXAMPLES - For amplifier envelope, the graphs show Amplitude (vertical axis) and Time (horizontal axis).
Top - shows key-pressed and key-released information (also called "Gate", equivalent to ADSR = 0%, NA, 100%, 0%).
Second ADSR = 0%, 80%, 50%, 60%. Perhaps for Piano.
Third ADSR = 10%, 20%, 75%, 40%. Perhaps for Strings.
Bottom ADSR = 20%, 40%, 25%, 20%. Perhaps for Brass.
OTHER ENVELOPE TYPES - Apart from the ADSR envelope, there are many other variations but they are usually based on the same principles.
One variant with 2 decays is the ADBDSR envelope; Attack, Decay-1, Break-Point, Decay-2, Sustain, Release [where Decay-1 is from full to the Break-Point level; and Decay-2 is from Break-Point level to Sustain level].
Another variant would be something like Rate-1, Level-1, Rate-2, Level-2, Rate-3, Sus, Rate-4 where the envelope is very flexible (Rate is the inverse of Time). Rate = High (a fast rate) is equivalent to Time = Low (a short time).

oh
well then
an envelope is an voltage contorler on a timbase line
