necessary abbreviations in English for audio post productors


-Encode: to convert message to a code, put data into digital form

-Decode: to extract a message from a code

-Daw: Digital Audio Workstation

-Post Production: making sound for movies

-Synthesizer: computerized electronic instrument capable of reproducing the sounds of various musical instruments; person or thing that synthesizes (also synthesiser)

-Codec: (compressor/decompressor) An abbreviation for the data compression schemes used by the ACM, AVI, MPEG, and QuickTime formats and the analog-to-digital converters on some sound cards. (Note that codecs only compress file size; to compress audio amplitude, apply a compressor effect.)

-ASIO: (Audio Stream In/Out) A standard for low-latency drivers, created by Steinberg Media Technologies.

-Bus:  In hardware mixers, a channel that lets you combine several other channels and output them together.

-DAT (digital audio tape) A standard two-track digital audio tape format. DAT tapes are sampled at 16 and 24 bits, and 32,000, 44,100, and 48,000 samples per second. (The latter is often described as DAT quality.)

-Latency: Measures the delay between user input and sound output from a computer. If latency is high, it produces an audible echo during recording, disrupting timing for musicians. To reduce latency, use sound cards with ASIO drivers.

-Mono: A monophonic signal, which contains only one sound source.

-Sample rate: The number of samples per second. Higher sample rates produce increased frequency response but require more disk space. To reproduce a given audio frequency, the sample rate must be at least double that frequency.

-SMPTE timecode: (Society of Motion Picture and Television Engineers timecode) A timing reference used to synchronize two devices. SMPTE timecode is divided into hours, minutes, seconds, and frames.

-sound card A hardware device that lets your computer play and record audio.

-sound wave A wave of air molecules. Humans can hear sound waves with frequencies of 20 to 20,000 Hz.

-stereo: A signal with a left and right channel, allowing for spatial placement of sounds.

-timecode: An audio or digital signal that synchronizes time between multiple devices. The most common forms are SMPTE and MIDI timecode.

-VST: Virtual Studio Technology, a plug-in format compatible with a wide variety of audio software. VST plug-ins provide audio effects such as compression and reverb; VSTi plug-ins provide virtual instruments such as samplers and synthesizers.
