Recording Audio is at heart of live, interactive webcasting. Below is a list of programs and resources we use at theWebcast Academy to learn about audio. The particular tools we use and how we make use of audio on this site is always evolving, so some of these materials may be outdated.

What is a Compressor?
A Compressor is a programmable gain(increase in signal strength or intensity) controller designed to decrease the difference in level between quiet and loud signals passing through it. The official definition is a programmable amplifier designed to decrease the difference in level between quiet and loud signals passing through it.
What is a Limiter?
A Limiter is a gain controller whose output goes so high but no further, and above a selectable point any increase in level at its input is not reflected in any increase in level at its output.
How do they Relate to Each Other?
These two functions are related, and can often come together. If dynamic range were a room then a compressor adjusts both the floor and the ceiling, and a limiter adjusts only the ceiling.
Post-production audio editing takes place after each webcast and in some cases makes the difference between producing audio that this 'listenable' or not.
