A multimedia application is interactive software that combines several types of media at once to convey information to an audience. Different types of media that can be used include:

• text
• images (photographs, illustrations)
• audio (music, sounds)
• video
• animation

Multimedia applications have brought about changes to the way people learn, work and play. They are now common in:

• e-learning both in education and the workplace
• entertainment
• modelling and simulation (for example, in virtual reality)
• conveying public information and promotional/advertising messages

The use of several different media components working together creates a more engaging and stimulating product, communicating more effectively to the end user.

Multimedia authoring is the process of combining many types of media (including video, text and audio) with interactivity to create an application and convey information to an audience.
