Sound is important because it can tell us about character, place, and time. It's important because it informs us and moves us in ways visuals can't, and because certain combinations of sound and visuals can evoke what neither can do alone. It's also potentially important because it can help to determine what we see.
Sound is important because it engages audiences: it helps deliver information, it increases the production value, it evokes emotional responses, it emphasises what's on the screen and is used to indicate mood. When put to good use, language, sound effects, music, and even silence, can elevate your video dramatically.
Audio files have several advantages for the delivery of distance learning courses. Audio files are also easy to create, easy to duplicate, and easy to use. Disadvantages of audio files include the fact that they are not interactive, and they do not provide the visual elements that many students desire.
Audio helps recall memories, enhance brain activity and stimulate the brain (Molyneux, 2007). Audio media is very useful in developing the listening skills of students (especially for language learning). Audio media supports distance learning. Audio media helps in memorization (music, mnemonics, etc).
The 3 elements that make up audio. In everyday life, the word 'audio' is often used casually to refer to speakers and other related components. However, audio can roughly be divided into 3 primary mechanisms (devices): player, amplifier, and speaker.

An example of multimedia is a web page with an animation. The basic types can be described as follows : Text, Graphics , Audio, Animation, Video, Graphic Objects (see: Computer graphics and visualization).
The five different multimedia which supports the education process are narrative media, interactive media, communicative media, adaptive media, and productive media.
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity.
The characteristics (Attributes) of sound are frequency, wavelength, amplitude and velocity.
We can say that sound is stored by waves. When the sound is needed to be used in any computer application, we need to converts the air vibrations of sound into an electrical signal, which is called digital signal- a stream of 0's and 1's. The process of conversing analog signals to digital signals is called digitizing.
If you're planning to digitize analog media yourself, you can do this by using:
- USB Cassette Converters. This is the easiest method to digitize your cassette.
- Tape Deck.
- An analog Player.
- Audio Connectors/Cables.
- A Digital Audio Workstation.
- Set up the analog player.
- Record the sound.
- Edit the Audio in the DAW.
Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
Images are a media type displayed as visual information. They can be drawings, paintings or photographs. Images are used to create interest and provide information. Photographs and other types of graphical data are designed specifically for display. An image on a screen is made up of dots called pixels.
There are three major groups of audio file formats: Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM; Formats with lossy compression, such as Opus, MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy (WMA lossy).
5 Applications for Your Multimedia System
- Text. This seems so obvious that many people forget about it.
- Audio. In many multimedia systems, audio provides a crucial link between text and images.
- Video. Another common type of media found in multimedia applications is video.
- Animation. Animation is a fun and common part of both online and desktop multimedia systems.
Audio input devices are used to capture sound. In some cases, an audio output device can be used as an input device, in order to capture produced sound. Audio input devices allow a user to send audio info to a computer for processing, recording, or carrying out commands.
“Audio Focus technology enables the selection of desired direction and attenuates the incoming sounds from other directions. When the strength of this effect is controlled dynamically — for example, together with the video camera's visual zooming — then the effect is called Audio Zoom.” — Nokia's Audio Zoom description.
Android
- Locate or download a recorder app on your phone and click to open.
- Press the Record button to begin recording.
- Press the Stop button to end recording.
- Tap your recording to share.
What is the best audio format for sound quality? A lossless audio file format is the best format for sound quality. These include FLAC, WAV, or AIFF. These types of files are considered “hi-res” because they are better or equal to CD-quality.
There are some audio medias which useful, such as : cassettes, micro cassettes, phonograph record, CD's, and audio card. Each of audio media has the advantages and limitations.
There are a number of different types of Audio files. The most common are Wave files (wav) and MPEG Layer-3 files (mp3). There are, however, many other audio file types discussed below.
WAV files are lossless, uncompressed, broadcast CD quality music files. WAV files are also the right choice for loops to be processed with Flash for web animations. Use MP3 files for web pages, web videos, in fact for anything on the Internet. An MP3 file is a compressed music file.
You can convert any audio file supported to Audacity to 3 files types: MP3, WAV, and Ogg Vorbis.
- From Audacity, click "Project" > Select "Import Audio."
- Navigate to the file you want to convert > Click [Open].
- Click "File."
- You have three "Export As" options.
- Name and place your file > Click [Save].
Uncompressed audio is audio without any compression applied to it. This includes audio recorded in PCM or WAV form. This results in a much smaller filesize then lossless or uncompressed audio. Lossy audio formats include AC3, DTS, AAC, MPEG-1/2/3, Vorbis, and Real Audio.
TWO TYPES OF AUDIO MEDIA Audio recordings come in two basic types; analog and digital. Analog refers to audio recorded using methods that replicate the original sound waves. Vinyl records and cassette tapes are examples of analog mediums.
