Audiovisual (AV) means possessing both a sound and a visual component, such as Slide-Tape presentations, church services and live theater productions.

Business presentations are also often audiovisual. In a typical presentation, the presenter provides the audio by speaking, and supplements it with a series of images projected onto a screen, either from a Slide Projector, or from a computer connected to a Projector using presentation software.

Audiovisual service providers frequently offer web streaming, video conferencing and live broadcast services.

Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology.
