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

27. Characteristics of a Sound: 1. Volume – intensity of a sound

28. Characteristics of a Sound: 2. Tone – the audible characteristic of a sound

36. Principles of Sound Design

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

41. Types of Transitions

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

46. Hearing vs. Listening

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?
