In computing, a plug-in (or add-in / addin, plugin, extension or add-on / addon) is a software component that adds a specific feature to an existing software application. When an application supports plug-ins, it enables customization. The common examples are the plug-ins used in web browsers to add new features such as search-engines, virus scanners, or the ability to utilize a new file type such as a new video format. Well-known browser plug-ins include the Adobe Flash Player, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution on a local Java virtual machine.
A record producer is an individual working within the music industry, whose job is to oversee and manage the recording (i.e. "production") of an artist's music. A producer has many roles that may include, but are not limited to, gathering ideas for the project, selecting songs and/or musicians, coaching the artist and musicians in the studio, controlling the recording sessions, and supervising the entire process through audio mixing (recorded music) and audio mastering. Producers also often take on a wider entrepreneurial role, with responsibility for the budget, schedules, contracts and negotiations.
