- 1. Audio Information and Media By: Lyka Marie B. Gumatay, LPT
- 2. What is an Audio? •sound, especially when recorded, transmitted, or reproduced
- 3. AUDIO MEDIA •media communication that uses audio or recordings to deliver and transfer information through the means of sound
- 5. Types of Audio Information 1. Radio Broadcast - live or recorded audio sent through radio waves to reach a wide audience
- 6. Types of Audio Information 2. Music - vocal or instrumental sounds combined in such a way as to produce beauty of form, harmony, and expression of emotion
- 7. Types of Audio Information 3. Sound Recording - recording of an interview, meeting, or any sound from the environment
- 8. Types of Audio Information 4. Sound Clips / Effects - any sound artificially reproduced to create an effect in a dramatic presentation (ex. sound of a storm, or a door)
- 9. Types of Audio Information 5. Audio Podcast - a digital audio or video file or recording, usually part of a themed series, that can be downloaded from a website to a media player or a computer
- 10. Ways to Store Audio Information
- 11. Ways to Store Audio Information: 1. Tape - magnetic tape on which sound can be recorded
- 12. Ways to Store Audio Information: 2. CD (Compact Disc) - a plastic-fabricated, circular medium for recording, storing, and playing back audio, video, and computer data
- 13. Ways to Store Audio Information: 3. USB Drive - an external flash drive, small enough to carry on a key ring, that can be used with any computer that has a USB Port
- 14. Ways to Store Audio Information: 4. Memory Card (aka Flash Memory Card or Storage Card) - is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable, or remote computing devices.
- 15. Ways to Store Audio Information: 5. Computer Hard Drive - secondary storage devices for storing audio file
- 16. Ways to Store Audio Information: 6. Internet / Cloud - websites or file repositories for retrieving audio files, and more precisely the files are stored in some datacenter full of servers that is connected to the Internet
- 18. Audio File Formats 1. MP3 (MPEG Audio Layer 3) - a common format for consumer audio, as well as a standard of digital audio compression for the transfer and playback of music on most digital audio players.
- 19. Audio File Formats 2. M4A / AAC (MPEG4 Audio / Advanced Audio Coding) - an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rate
- 20. Audio File Formats 3. WAV - is a Microsoft audio file format standard for storing an audio bitstream on PCs. It has become a standard file format for game sounds, among others
- 21. Audio File Formats 4. WMA (Windows Media Audio) - is an audio data compression technology developed by Microsoft and used with Windows Media Player
- 22. Units of Sound
- 23. Decibel •or simply dB •noise of sound measurement
- 24. Hertz • or simply Hz • unit of sound frequency
- 26. Characteristics and Purposes of Sound
- 27. Characteristics of a Sound: 1. Volume – intensity of a sound
- 28. Characteristics of a Sound: 2. Tone – the audible characteristic of a sound
- 29. Characteristics of a Sound: 3. Pitch - is how high or low a sound is
- 30. Characteristics of a Sound: 4. Loudness - refers to the magnitude of the sound heard
- 31. Purposes of a Sound: •Give instruction or information. •Provide feedback. •To personalize or customize
- 33. Elements of Sound Design: 1. Dialogue - speech, conversation, voice-over
- 34. Elements of Sound Design: 2. Sound Effects – any sound other than music or dialogue
- 35. Elements of Sound Design: 3. Music – vocal or instrumental sounds (or both) combined in such a way as to produce beauty of form, harmony, and expression of emotion
- 37. Principles of Sound Design: 1. Mixing – the combination, balance and control of multiple sound elements
- 38. Principles of Sound Design: 2. Pace – time control, editing, order of events (linear, non-linear or multi-linear)
- 39. Principles of Sound Design: 3. Stereo Imaging – Using left and right channel for depth. This refers to the aspect of sound recording and reproduction.
- 40. Principles of Sound Design: 4. Transition – how you get from one segment or element to another
- 42. Types of Transitions: 1. Segue – one element stops, the next begins (“cut” in film)
- 43. Types of Transitions: 2. Cross-fade – one element fades out, the next fades in, and they overlap on the way
- 44. Types of Transitions: 3. V-Fade – first element fades to inaudible before the second elements begins
- 45. Types of Transitions: 4. Waterfall – As first element fades out, the second element begins at full volume. Better for voice transitions, than for effects
- 47. Hearing •the act of perceiving sound by the ear
- 48. Listening •requires concentration so that your brain processes meaning from words and sentences. Listening leads to learning.
- 49. So are you listening or just hearing?
