It is a software interface standard developed by Steinberg that allows audio plugins to be used within a host application, like a digital audio workstation (DAW).
Here's a breakdown:
* Virtual: It refers to the fact that VST plugins are software-based and run within a computer, not as physical hardware.
* Studio: Indicates the intended use within a music production environment.
* Technology: It encompasses the technical specifications and protocols that define how VST plugins interact with host applications.
Essentially, VST is a way for software developers to create and distribute audio effects, instruments, and other processing tools that can be integrated into a wide range of music production software.
