Digital audio refers to representing sound numerically by decomposing analogue sound waves into samples. This differs from analogue media like tapes which store sound physically. Interactive features in digital publications allow two-way communication, like responding to instructions from the user to pause, rewind or fast forward content. They present audio, visual, text and other media content that responds to user actions. While video and graphics provide visual aids, disadvantages include potential poor quality, digression from text, and some graphics not adding useful information.
2. Audio
sound, especially when recorded, transmitted, or reproduced “audio
equipment”
In sound recording and reproduction systems, digital audio refers to a
digital representation of the audio waveform for processing, storage or
transmission. When analogue sound waves are stored in digital form, each
digital audio file can be decomposed into a series of samples.
Digital music (sometimes referred to as digital audio) is a method of
representing sound as numerical values. This differs from analogue media
such as magnetic tapes or vinyl records for instance where the sound is
stored in a physical form. In the0case of cassette tapes, this information is
stored magnetically.
3. Audio/video
audio is a sound that can talk to the reader about the article and video will be
able to show people that are deaf what's going on instead of the audio
speaking audio-visual (AV) means possessing both a sound and visual
component, such as slide tapes presentations, films, television programs,
church services and live theatre productions. Business presentations are also
often audio-visual.
4. graphics
the products of the graphic arts, especially commercial design or
illustration.
the use of diagrams in calculation and design.
Images that are generated by a computer are called computer graphics.
Examples are photographs, drawings, line art, graphs, diagrams,
typograph, numbers, symbols, geometric designs, maps, engineering
drawings, or other images. Graphics often combine text, illustration, and
colour.
5. Definition of interactive features
of or relating to a two-way system of electronic communications, as by
means of television or computer: interactive communications between
families using two-way cable television.
Interactive features are when you give the computer or a device and
instruction.
For example pausing rewinding fast forwarding playing
Interactive media normally refers to products and services on digital
computer based systems which respond to the user’s actions by presenting
content such as text, moving image, animation, video, audio, and video
games.
