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.

Another audiovisual expression is the visual presentation of sound (visual music).
