Taken from The Daisy Consortium Glossary Glossary of digital and analogue audio terminology (Dec. 23, 1999) http://www.daisy.org/questions/glossary.htm NOTE:(This glossary is made by Lars Sönnebo lars.sonnebo@tpb.se , The Swedish Library of Talking Books and Braille)........a european........ Real-time (process) [WCAG20] 06-20-2002 The Daisy Consortium This term is often written as "realtime" or "real-time". The expression indicates that a process is happening "live", i.e. at the same time as something else. For example, with some audio CoDecs, it is possible to "compress in real time", which in this case can indicate that the digital audio data compression is performed by the computer at the same time as the digitisation and data storing is talking place. To be a true real time process, it must be possible to do the work as fast as – or preferable faster – than the rate at which input data is coming in. If the real time process can not keep up with the tempo of "real life", it is no longer a real-time process.
