Audio

anything related to the documentation and transmission of sound

Audio

one of the resources of media and information, along with text, visual, and motion

Audio Media

the media communication that uses audio equipment to report, document, and deliver information through the means of sound

Audio Media

May also refer to audio formats such as analog tape cassettes, digital compact discs, and computer files containing audio

Audio Information

the file or sound created and transferred by using high-fidelity waves that are heard through certain audio tools

• Radio Broadcast

• Music

• Sound Recording

• Sound Clip/Sound Effect

• Audio Podcast

Types and Categories of Audio Information

Radio Broadcast

the act of sending a live or recorded audio through radio waves meant for a large group of listeners

Music

an artistic form of auditory communication incorporating instrumental or vocal tones in a structured and continuous manner

Sound Recording

the encoding of any sound from the surroundings; the act or procedure of making a record of a certain sound

Sound Clip/Sound Effect

the sound, aside from dialogue and music, artificially made to create an effect in a movie, play, or other broadcast production

Audio Podcast

an episodic series of digital audio or video file or recording that can be downloaded by a user from a website to a media player or computer to listen

• Tape

• Compact Disc

• USB Flash Drive

• Memory Card

• Computer Hard Drive

• Internet/Cloud

Ways of Storing Audio Files

Tape

a magnetic tape sound recording format on which sound can be documented

Compact Disc

a plastic-fabricated, circular tool on which audio, video, and other digital information is recorded, stored, and played back

USB Flash Drive

an external hard disk drive, small enough to fit on a keychain, that can be plugged into the computer’s USB port

Memory Card

a small, flat flash drive used to save data such as audio files, pictures, texts, and videos for use on small, portable, or remote computing devices

Computer Hard Drive

a secondary data storage device for saving digital data

Internet/Cloud

a wide network of remote servers in the internet meant to operate as storage and retrieval of audio files and other computer data

• MP3 (MPEG Audio Layer 3)

• M4A/AAC (MPEG-4 Audio/Advanced Audio Coding)

• WAV (Waveform Audio File Format)

• WMA (Windows Media Audio)

Audio File Formats

MP3 (MPEG Audio Layer 3)

a coding format for consumer audio, as well as a mean of sound sequence compression for the transmission and playback of music on most digital audio players

M4A/AAC (MPEG-4 Audio/Advanced Audio Coding)

a file extension for lossy digital audio compression

WAV (Waveform Audio File Format)

the Microsoft audio file format standard used for the storage of digital audio data on personal computers

WMA (Windows Media Audio)

a file extension developed by Microsoft and used with Windows Media Player

Hearing

The act of perceiving sound by the ear.

Listening

• Something you consciously choose to do. 

• Requires concentration so that the brain processes meaning from words and sentences. 

• Volume

• Tone

• Pitch

• Loudness

Characteristics of a Sound

Volume

the force of a sound

Tone

the musical or vocal sound of a definite quality

Pitch

the degree of highness or lowness of a sound

Loudness

the feature of a sound that determines the degree of the auditory sensation produced

Purposes of Using Sounds or Audio Media

• These enable the learners to listen to the ideas and views of the experts and other reliable people; 

• These allow learners to listen to learning materials, like speeches; 

• These serve as alternative guides for the learners when they are doing their tasks, such as experiments; and 

• These grant the learners audio files of important past events or sounds from the settings that the learners cannot personally visit. 

Sound Design

The vivid use of sound during a production in connection to the images and contents of the story to create an emotional response.

Sound

sound is an essential part of any movie, play, or broadcast production.

• Dialogue

• Sound Effect

• Music

• Silence

Elements of Sound Design

Dialogue

a composition in the form of conversation between two people

Sound Effect

the sound, aside from dialogue and music, artificially made to create an effect in a movie, play, or broadcast production

Music

an instrumental or a vocal sound that conveys emotions and ideas in significant forms through the elements of color, harmony, melody, and rhythm

Silence

the complete absence of noise or sound

• Mixing

• Pace

• Transition

• Stereo Imaging

Principle of Sound Design

Mixing

the balance, combination, and control of numerous sound elements

Pace

the editing and the time control of sound design

Linear

the sounds that are permanent, used once, and will be in the same place

Non-linear

the sounds that are much more open in comparison to linear sounds

Transition

the process of getting from one element or fragment of sound design to another; it has various types:

Segue

an uninterrupted movement from one piece of music to another

Cross-Fade

the smooth transition of a sound between two side-by-side audio files on the same track

V-Fade

a switch from one volume level to another softer or louder level

Fade to Black

a type of V-Fade which has some silence between the elements of sound design

Stereo Imaging

the feature of sound documentation and duplication concerning the supposed spatial locations of the sound sources, both sideways and in-depth.
