Sureno i have a few, i'll add to the letters that have the least words
Here goes:
E
Early reflections - initial sound reflections from walls, floors and ceilings following a sound created in an acoustically reflective environment
Effect - Device for treating an audio signal in order to change it in some creative way. Effects often involve the use of delay circuits and include suck treatments as reverb and echo.
Effects Loop - Connection system that allows an external signal processor to be connected into the audio chain
Effects return - Additional mixer input designed to accommodate the output from an effects unit
Encode/decode - term used to describe a system that requires a signal to be processed prior to recording. The process is then reversed during playback.
Enhancer - Device designed to brighteen audio material using techniques such as dynamic equalisation, phase shifting and harmonic generation.
Event - In MIDI terms, an event is a single unit of MIDI data, such as a note being turned on or off, a piece of controller information , a program change message and so on.
Expander - Device designed to decrease the levels of low-level signals and increase the levels of high-level signals, thus increasing the dynamic range of the signal..
I
Initialise - To restore a piece of equipment to its factory default settings automatically.
Insert Point - Connector that allows an external processor to be patched into a signal path so that the signal flows through the external processor
Interface - Device that acts as an intermediary between two or more other pieces of equipment. For example, a MIDI interface enables a computer to communicate with MIDI instruments and keyboards.
I/O - The part of a system that handles inputs and outputs, usally in the digital domain.
IPS - Abbreviation of inches per second, used to describe tape speed.
J
Jack - Common audio connector. May be mono or stereo.
N
Normalising - The process of increasing the level of an audio file so taht its loudest peak reaches exactly digital full scale.
Noise reduction - System used to reduce analogue tape noise or to reduce the level of hiss present in a recording. Noise-reduction systems generally employ a coding process while recording and an inverse decoding process during playback. Examples are Dolby A,B,C,S and SR as well as dbx type I and type II.
Noise shaping - System used to create digital dither such that any added noise is shifted into those parts of the audio spectrum where the human ear is least sensitive.
O
Ohm - Unit of electrical resistance
Omni - Literally "all", omni refers to a microphone that is equally sensitive in all directions or to the MIDI mode where data on all channels is recognised.
Open circuit - Break in an electrical circuit that prevents current from flowing.
Overdub - To add another part to a multitrack recording or to replace one of the existing parts.
U
Unbalanced - Term used to describe a two-wire electrical signal connection where the inner (or hot, or positive) conductor is usally surrounded by the cold (or negative) conductor, which forms a screen against interference.
Unison - Term used to describe the playing of a melody using two or more different instruments or voices simultaneously.
V
Voice - Term used to indicate the capacity of a synthesiser to paly a single musical note. An istrument capable of playing 16 Simultaneous notes is said to be a 16-voice instrument.
W
Wah-wah pedal - Guitar effects device where a bandpass filter is varied in frequency by means of a pedal control
Watt - SI unit of electrical power
Waveform - Graphic representation of the way in which a sound of eletrical wave varies with time.
Y
Y-Lead - Lead split so that one source can feed two destinations. Y-leads may also be used in console insert points, in which case a stereo jack plug at one end of the lead is split into two monos at the other.
Z
Zipper Noise - Audible steps that occur when a parameter is being varied in a digital audio processor.
This was taken from a book. Sorry for any typo as i was reading the words as i was typing without confirmation
