BEAT  --  The constant, consistent pulse in music.

RHYTHM  --  Patterns that create the movement of sound.

TEMPO  --  The speed of music.

PITCH  --  Musical tones all have pitches.  Pitched tones are also called musical notes.  The pitch of a musical note refers to how high or low the note is in the overall pitch register.

FREQUENCY  --  A measurement of the number of sound waves per second.  

HERTZ  --  Abbreviated Hz, Hertz is the measurement of frequency.

INTENSITY  --  The volume of sound.  How loud or soft the sound is.

AMPLITUDE  --  A measurement of the height of a sound waves.

DECIBELS  --  Abbreviated dB. Decibels is the measurement of intensity (volume).

TONE QUALITY  --  The property that enables the ear to distinguish between different instruments playing the same note.

FUNDAMENTAL FREQUENCY  --  The first mode of vibration, it determines the pitch we hear.  Also known as the first harmonic.

PARTIALS  --  Also known as harmonics, each of the various modes of vibration accompanying the fundamental frequency or first harmonic.

HARMONIC SERIES  --  The succession of partials (harmonics) produced by a musical tone.

OSCILLATOR  --  The sound producing component of a synthesizer.  The oscillator is capable of producing frequency and harmonic content.

WAVE FORM  --  There are four simple wave forms produced by an oscillator.  They are sine, square, triangle, and sawtooth.  See figure below for examples:

RECORDING  --  The transmittal of sound waves onto a device capable of preserving and reproducing that sound.

ANALOG SIGNAL --  A "continuous periodic signal" that is like a wave in its periodic nature.  Analog media stores the waves themselves as a continuous electrical charge.  Magnetic tape is the most common analog medium.

DIGITAL SIGNAL  --  Digital media store a numerical representation of the wave using a code consisting of only zeros and ones, called binary code.  In the early days of digital recording, the common way to store this binary information was on magnetic tape known as Digital Audiotape, or DAT.

OVERDUBBING  --  The recording process of adding live tracks after the initial recording.

MULTITRACK  --  The ability to record instruments on individual tracks.

MIDI  --  Musical Instrument Digital Interface.  A system that allows electronic musical instruments and computers to send instructions to each other.

BIT  --  One single point of information  (Binary Digit)

NIBBLE  --  A four bit word

BYTE  --  An eight bit word  (By Eight)

BINARY CODE  --  A system of 1's and 0's used by computer processors.

EDIT WINDOW -- The Pro Tools window in which the audio signals are viewed and editable.

MIXER WINDOW -- The Pro Tools window which serves as the virtual mixer, allowing for inserts, sends and fader control.

EQ -- Short for Equalization, it is the process of boosting or cutting certain frequencies or groups of frequencies in a sound.

Q VALUE -- Narrows or broadens the range of frequencies affected by a particular EQ band.

HIGH PASS -- Lets the high frequencies through and blocks the low frequencies.

LOW PASS -- Lets the low frequencies through and defeats the highs.

HIGH SHELF -- Controls specific frequency and all frequencies above it.  This is similar to your stereo's bass and treble knobs.)

LOW SHELF -- Affects a certain frequency and all others below it.

PARAMETRIC -- Lets you boost or cut a specific frequency (to boost just one little part of a sound).  Also known as a peak filter.

NOTCH -- The opposite of a peak filter: this lets you remove a specific frequency.

REVERB -- Concerns the reflections of sound waves from the surface of the enclosure in which the sound is produced.  It is a naturally occurring phenomenon.

COMPRESSION -- A type of dynamic effect you can use to affect the levels of a track or indeed a whole piece of music.  It automatically stops volume from rising too high.

LF -- Low Frequencies

LMF -- Low Mid Frequencies

MF -- Mid Frequencies

HMF -- High Mid Frequencies

HF -- High Frequencies
