Audio Media  Audio Audio is defined as anything connected to sound, specifically when received, recorded, transferred, or duplicated (HarperCollins, n.d.). It is anything related to the documentation and transmission of sound (Cambridge University, n.d.). Audio is one of the resources of media and information, along with text, visual, and motion  Audio Media Audio Media refers to the media communication that uses audio equipment to report, document, and deliver information through the means of sound. It may also refer to audio formats such as analog tape cassettes, digital compact discs, and computer files containing audio. On the other hand, audio information is the file or sound created and transferred by using high fidelity waves that are heard through certain audio tools.  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 (Merriam- Webster, n.d.)  ❖ 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 (Oxford University, n.d.) ❖ 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  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  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 8  ❖ 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  What's the difference between lossy and compression? There are two methods of compression – lossy and lossless. Lossy reduces file size by permanently removing some of the original data. Lossless reduces file size by removing unnecessary metadata.  Characteristics of a Sound ❖ Volume - the force of a sound ❖ Tone - the musical or vocal sound of a definite quality (Merriam- Webster, n.d.) ❖ Pitch - the degree of highness or lowness of a sound (Oxford University, n.d.) ❖ Loudness - the feature of a sound that determines the degree of the auditory sensation produced (Merriam-Webster, n.d.) 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.  Elements and Principles 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 (Oxford University, n.d.) ❖ 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 – the balance, combination, and control of numerous sound elements ❖ Pace – the editing and the time control of sound design; it has numerous categories: o Linear – the sounds that are permanent, used once, and will be in the same place o Non-Linear – the sounds that are much more open in comparison to linear sounds Multi-Linear  ❖ Transition – the process of getting from one element or fragment of sound design to another; it has various types: o Segue – an uninterrupted movement from one piece of music to another o Cross-Fade – the smooth transition of a sound between two side by side audio files on the same track o V-Fade – a switch from one volume level to another softer or louder level o 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.  Modified True or False: Read each statement carefully. Write True if the statement is correct, but if it is false, write the word that makes the statement wrong followed by the correction. __________ 1.
