A Beginner's Guide To Digital Music-Making
A scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale.
C Major Scale:
A chord, in music, is any harmonic set of usually three or more notes (also called "pitches") that is heard as if sounding simultaneously.
Usually three or more notes played together.
The "speed" of the music or beats per minute.
Stereo is a method of sound reproduction that creates an illusion of multi-directional audible perspective. This is usually achieved by using two or more independent audio channels through a configuration of two or more loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing.
It is often contrasted with mono sound, where audio is heard as coming from one position, often centered in the sound field.
The distribution of a sound signal into a new stereo or multi-channel sound field determined by a pan control setting (ie. some sounds comes from the left speaker, some come from the right speaker, and some come from both [sounds like it comes from the middle]).
You might pan guitar #1 one to the right, guitar #2 to the left, and leave the bass, drums, and vocals centered (coming out of both speakers equally).
Double tracking or vocal doubling is an audio recording technique in which a performer sings or plays along with his or her own prerecorded performance, usually to produce a stronger or "bigger" sound than can be obtained with a single voice or instrument.
Audio filters can boost, pass cut some frequency ranges
An audio processor which measures and alters pitch in vocal and instrumental music recording and performances. It was originally intended to disguise or correct off-key inaccuracies, allowing vocal tracks to be perfectly tuned despite originally being slightly off-key. The processor slightly shifts pitches to the nearest semitone (or note).
In digital music processing technology, quantization is the process of transforming performed musical notes, which may have some imprecision due to expressive performance, to an underlying musical representation that eliminates this imprecision. The process results in notes being set on beats and on exact fractions of beats.
In Short: if you quantize your performance, it cleans up the timing of your notes.
When an effect is automated, the console or DAW remembers the audio engineer's adjustment of the effect.

I pulled many of the definitions from various sites from the internet (mostly wikipedia).
