Editing Phone-in (section)

==Technology==
The caller is connected via a [[telephone hybrid]], which connects the [[telephone line]] to the [[Mixing console|audio console]] through [[impedance matching]], or more modernly through [[digital signal processing]], which can improve the perceived [[Sound quality|audio quality]] of the call.  [[Telephone call]]s are often organised through a system which also provides [[broadcast automation]], with an [[Secretary|administrative assistant]] answering calls and entering [[calling party|caller]] information on a [[personal computer]], which also displays on the [[Radio personality|radio presenter]]'s screen.  A [[profanity delay]] is often used to keep [[profanity]] and other inappropriate material off the air.  For [[competition|contest]]s, the [[conversation]] can be recorded and [[Digital audio editor|edited]] "on the fly", before playback on the air just a few minutes later.
