Plug-in
Definition
Software that extends the functionality of a DAW by adding virtual instruments, effects processors, or utility tools. Common formats include VST3, AU, and AAX.
In Simple Terms
Software that adds instruments or effects to your DAW-compressors, reverbs, synthesizers, guitar amps. They extend what your DAW can do, like apps extend what your phone can do.
In Practice
A compressor plug-in inserted on a vocal channel processes the signal in real time within the DAW. Industry standards like the FabFilter Pro-C2 or Universal Audio SSL G-Bus emulation are common choices.
