AUX is an abbreviation for "auxiliary." As a noun, it commonly refers to an auxiliary port, a device or connection point that allows additional audio or video inputs to be connected to a main system. Typically found in electronic devices like stereos, car audio systems, televisions, or speakers, the AUX port is used to transmit audio signals from external sources, such as smartphones, MP3 players, or computers, to the main system for playback.
The term "AUX" can also be used as a verb, meaning to provide additional support or assistance. In this sense, it is often used to describe a secondary or backup function or resource that supplements or enhances the primary one.
In the realm of music, AUX can also refer to a sound mixing technique called "auxiliary send." In audio mixing consoles, an auxiliary send is a dedicated output that allows a portion of a signal to be sent to an external effects processor or a separate mix. This enables the mixing engineer to add different effects or create a separate monitor mix for performers.
Overall, whether as a noun or verb, AUX carries the connotation of providing supplementary or auxiliary functions to enhance the primary system or process with additional inputs, support, or effects.
