WAVEFORM
A usually graphic representation of the shape of a wave that indicates its characteristics (as
frequency and amplitude). When talking about synthesizers, the term generally refers to the most
common types of waveforms, such as the sine, triangle, sawtooth, and pulse waves. It can also
refer to digital waveforms which are rendered from pre-recorded samples.
WORD CLOCK
A word clock is a device used to create a regular pulse used to synchronize other devices, such as
digital audio tape machines and compact disc players, which interconnect via digital audio. S/PDIF,
AES/EBU, ADAT and other formats use a word clock. A word clock neither produces nor uses
timecode; it is used entirely to keep a perfectly-timed and constant bitrate to avoid data errors.
