  1. MODULE 6 AUDIO MEDIA BONA MAE S. ORDANZA

  2. CONTENT Unlocking the Terms: Audio- is the process of hearing and listening. It is the transmission, reception or reproduction of sounds. Audio media- is a medium that is narrated, recorded with the use of audio equipment. It is non projected and enhances visual and effectiveness of a presentation. Audio format- is a medium for storing sound and music. It refers to physical recording media used to store data.

  3. Hearing-is a process in which sound waves entering the outer ear are transmitted to the eardrum, converted into mechanical vibrations in the middle ear, and changed in the inner ear into nerve impulses that travel to the brain. Listening- begins with someone’s awareness of and attention to sounds or speech patterns,proceeds to identification and recognition of specific auditory signals, and ends in comprehension.

  4. TECHNIQUES TO IMPROVE STUDENT’S LISTENING ABILITIES Good listening is very critical between student’s and teacher relationship in the classroom. Directed Listening. Following Directions. Listening to the main ideas, details, or interference. Using context in listening. Analyzing the structure of a presentation. Distinguishing between relevant and irrelevant information.

  5. TYPES OF AUDIO RECORDING ANALOG RECORDING It comes from a Greek term, ana which means “according to” and logos “relationship”. It is a technique used to store signals of audio or video information for later playback. Analog recording methods store audio signals as a continual wave in or on the media. The wave might be stored as a physical texture on a phonograph record, or a fluctuation in the field of strength of a magnetic recording.

  6. AUDIO FORMAT AUDIO TAPES A. Compact Cassette - Cassette is a French word meaning “little box”. B. Micro Cassette - is the smaller version of standard audio cassette.

  7. PHONOGRAPH RECORDS - known as vinyl record, vinyl, or simply record. It is an analog storage medium consisting of a flat disc with an inscribed modulated spiral groove usually starting near periphery and ending near the centre of the disc.

  8. 3. LONG PLAYING - Also known as LP. Are 33% ½ rpm vinyl phonograph records, generally either 10 or12 inches in diameter. They were first introduced in 1948, and served as a primary release format for recorded music until the compact disc began to significantly displace them by1988, and eventually leaving the main stream in 1991.

  9. B. DIGITAL RECORDING • - it uses digital signals for sound reproduction. It uses the simplicity of the binary code, the power on and the power off. • AUDIO FORMAT • Compact Disc • -also known as a CD, is an optical disc used to store digital data, originally developed for storing digital audio. It has a diameter of 120 mm and can hold up to 80 minutes of audio.

  10. MINI COMPACT DISC - or “Pocket” CDs are compact discs with a smaller form factor and half the capacity. It has various diameters ranging from 60-80 mm. TYPES OF COMPACT DISC CD ROM- data storage CD-R- write-once audio and data storage CD-RW- rewritable media VCD- video compact disk SVCD- super video compact disc Picture CD CD-I and enhanced CD

  11. 3. TRACK - On an optical disc, a track (CD) or title (DVD) is a subdivision of it’s content. Specifically, it has a consecutive set of sectors on the disc containing a block of data. One session may contain one or more tracks of the same or different types. There are several kinds of tracks, and there is also a sub-track index for finding points within a track.

  12. 4. MPEG-1 Audio Layer 3 - More commonly referred to as MP3, is a digital audio encoding format using a form of lousy data compression. - It is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered high fidelity audio by audiophiles.

  13. 5. AUDIO CARDS - A computer expansion card that facilitates the input and output of audio signals to/from a computer under control of computer programs. ADVANTAGES Direct learning from the speaker Improve the listening skills of the students Catches and enhances the attention of the students Handy Can be played over and over again Retrievable information Serving as a verbal record for interviews

  14. LIMITATIONS Limited attention concentration One-way communication Requires good listening skills Basic method of teaching is repetition New materials necessitated extensive use of equipment with all associated problems of black-out, and worn out cassette tape. Equipment could break down Analog format is not sophisticated equipment of today Hardware involved extra time, worry and problems

  15. EQUIPMENT FOR RECORDING Cassette deck- is a type of tape recorder for playing or recording audio compact cassettes. Microphones-is sometimes referred to as a mic or mike, is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. They are used in many applications for recording voice.

  16. Lavaliere microphone- is made for hands-free operation. These small microphones are worn on the body and held in place either with a lanyard orn around the neck or a clip fastened to clothing. B. Wireless microphone- is one in which the artist is not limited by a cable.

  17. Contact microphone- is designed to pick up vibrations directly from a solid surface or object, as opposed to sound vibrations carried through air. Parabolic microphone- uses a parabolic reflector to collect and focus sound waves onto a microphone receiver, in much the same way that a parabolic antena does with radio waves.

  18. TAPE RECORDER-is an audio storage device that records and plays back sound using magnetic tape, either wound on a reel or in a cassette, for storage. It records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signals. 4. CD PLAYER- an electronic device that plays audio Compact Discs.

  19. RADIO RECEIVERS- a device that converts radio waves into intelligible sounds or other perceptible signals. MAGNETIC RECORDING TAPE- a device for storing information, in which signals are recorded by lining up small bits of magnetic materials in the coating on the tape.

  20. AV RECEIVERS- or audio-video receivers are one of the many consumer electronics components typically found within a home theater system. These were generally called stereo receivers. AMPLIFIERS-or simply amp, is any device that changes, usually increases, the amplitude of a signal. The “signal” is usually voltage or current.

  21. MIXING CONSOLES- or audio mixer, also called a sound board, is an electronic device for combining, routing, and changing the level, timbre / dynamics of audio signals. EFFECTS UNITS- are device that affect the sound of an electric instrument or other audio source when plugged in to the electrical signal path the instrument or source sends, most often an electric guitar or bass guitar.

  22. LOUDSPEAKERS-is an electro acoustical transducer that converts an electrical signal to sound. The term loudspeaker can refer to individual transducers, or to complete systems consisting of an enclosure incorporating one or more drivers and electrical filter components.

  23. APPLICATION OF AUDIO RECORDING SOUND POETRY. A method that a teacher may use in order to let children hear and read poetry written especially for them. TEXT SOUND. Another way to teach a child repeating a word over and over to enable the child become familiar with how a word sounds and feels. VOICE COMPOSITION. It is more on non-speech sounds with voices such as whimpers, sighs, groans, moans, laughing, crying, wailing, and about any other human non-speech sound generated by the voice can be used as a compositional element.

  24. ART AND PERFORMANCE TAPES. A combination of both text-sound and voice composition accompanied with other curricular activities. AUDIO DRAMA. Simply a play and dramatization on tape READ ALONG BOOKS. This a book with an audio cassette. These book’s content is performed by professional reader. SOUND EDITING PROGRAM. Is used to create interesting things with a computer and a tape recorder.. The sound is edited with sections re-arrange, particular words edited out, and other words inserted and may sometimes distort original messages.

  25. 8. PODCASTING. According to WikiPedia, a podcast is “a web feed of audio files that is placed on the internet for anyone to download. I t’s usually possible to download the files directly from the website, just as one would normally do; however, special programs called pod catchers exist that let users subscribe to podcasts in order to automatically download and store the media files for later playback.”

  26. TIPS TO BETTER AUDIO RECORDING Find the recording distances and positions for the speaker in relation to the microphone (usually 6 to 18 inches directly in front of the mike). Speak in a clear, distinct conversational manner. Eliminate all undesired background noises. Do not move the microphone during recording because of it’s sensitivity. Make a provision against interruption.
