  1. Multimedia Enabling Software

  2. The Human Perceptual System • Since the multimedia systems are intended to be used by human, it is a pragmatic approach to design multimedia systems based on the needs and capabilities of human perceptual systems. • Many multimedia are not designed based on these requirements.

  3. Important Notes on Audio • In playing either digital or MIDI audio on the Web, just do one of the following things: • Wait until the entire sound file is downloaded to your computer, then play it back. • You can play downloading sound file as soon as enough of the sound is cached in the computer’s buffer and downloading continue to fill the buffer faster.

  4. Components of Human Perceptual System • Human perceptual system consists of the: • Human Visual System • Human Auditory System • How these systems works is still not completely understood and is a subject of continuing research effort.

  5. Introduction to Multimedia Authoring Tools • The rapid development of multimedia operating environment has been matched with the development of software tools. These tools could be categorised as: • Image creation, preparation and editing tools. • Audio preparation and editing tools. • Video preparation and editing tools • Animation tools • 3D tools

  6. Introduction to Multimedia Authoring Tools • These tools are used for various media creation and preparation activity. • In-depth understanding of how text, graphic, audio, and video is required in operating of these tools.

  7. Introduction to Multimedia Authoring Tools • Multimedia authoring tools provide the important framework needed for organising and editing the elements multimedia project, including graphics, sounds, animation, and video clips. • Authoring tools are used for designing interactivity and the user interface.

  8. Types of Authoring Tools • There are mainly three types of authoring tool:- • Card-based tool • Icon-based tool • Time-based tool • Some authoring tool may combine different features of the three types.

  9. Types of Authoring Tools • Prepare the tool that best fit the job you want to do with your multimedia projects. • Authoring tools are being added new features and increase performance. • It is important that you study the software product reviews in computer trade journals and talk to the current users before deciding best tool.

  10. Editing Features • The elements of multimedia need to be created, edited, and converted to standard file formats, and the specialized applications. • The more editors your authoring system has, the fewer the specialised tools will be needed.

  11. Programming Features • Multimedia authoring systems offer one or more of the following approaches, which are:- • Visual programming with icons, and others. • Programming with scripting language. • Programming with traditional languages such as C or Basic.

  12. Sound Editing Tools • Tools used in editing sound (digital or MIDI). • You can cut, copy, paste, and edit segments of the sound, something that you can’t do in a real time (that is, with the music playing). • Example of the editing tool is Audacity.

  13. Animation • Animations and digital video movies are sequences of bitmapped graphic scenes (frames), rapidly played back. • But animations can be made within the authoring system by rapidly changing the location of objects to generate an appearance of motion
