I. Introduction

A. Chapter 4:  Sound, Animation, and Video

B. Sound

C. Animation

D. Spreadsheet Tools for Presentation Graphics

II. Chapter 4:  Sound

Classes of Multimedia Sound

Any ASCII text may be read and spoken by Simple Text

Dr. Jones lives at 234 Oak Dr. and earns $125,000 per year.

Speech to ACSII Text - IBM ViaVoice

1. Plug in the ViaVoice Microphone and speaker jack

2. Open IBM SpeakPad

3. Read the paragraph above in clear voice. Results:

In Chapter III you learn how text and graphics are used in multimedia titles. In this chapter you will learn about the other elements: Sound, animation, and video. These elements are relatively new to desktop computers and can greatly enhance the effectiveness of multimedia titles. As you study the this, keep in mind that the position of which elements to use it is often a trade-off between cost, time, and a fact.

Conclude: ViaVoice is > 99% accurate, but errors can be embarrassing.

CD-ROM Audio Disks can be played using the Apple CD Audio Player



Sound Bytes (Audio Alerts)

Let's try to make our own Alert soundbyte, convert to AIFF, and play it.

1. Open Monitors & Sound in the Control Panels
2. In "Sound Monitoring Source", select "Sound in"
3. Select "Alerts" button and click "Add"
4. Verify Microphone operation by blowing into it
5. Record your Alert soundbyte, give it a name and save it.
6. Copy it from your system folder to your project folder
7. Open it with SoundApp, edit it, and save it as an .mov file.

Audio file types include

  • MIDI
  • audio/rmf
  • RealPlayer™
  • WAVE Audio
  • AIFF Audio
  • ULAW Audio
  • QuickTime Audio MPEG
  • audio/x-rmf
  • MP3 Streaming Audio 

MIDI Music

  • MIDI = Musical Instrument Digital Interface
  • MIDI is to music as vector graphics is to graphics
  • In vector graphics, we store the instructions as to how to draw an object
  • In MIDI, we store the instructions as to what note, volume, duration, etc to store
  • As a result, MIDI files are far smaller than analog recordings
  • Many famous performers and composers use MIDI
    • Stevie Wonder
    • Philip Glass


III. Animation

  • Animation comes in two classes
    • 2D
    • 3D

2D Animation  

  • 2D Animation may be further divided into the two classes
    • Cel animation
    • Path animation
  • Cel animation (from celluloid transparent sheets)
    • Requires a stationary background
    • Animated objects are superimposed on the scene
    • Example:  Yearn to Learn education CD-ROM
  • Path animation involves three elements
    • A stationary background
    • An object definition (ball, rocket, etc.)
    • A path along which the object is to move by tweening

3D Animation

  • The tool of choice is Swivel3D
    • Supports sophisticated 3D design
    • Supports tweening and animation

  • Demonstrate


IV. Spreadsheet Tools for Presentation Graphics

Presentation Graphics is probably the largest single category

Particularly useful in business presentations

  • Organizational structure
  • Distributions of business expenses
  • Sources of income
  • Growth patterns

Other institutions make widespread use of presentation graphics

  • Federal Government
  • Consider the UW-P CSci program review

  We will demonstrate three spreadsheet tools for generating presentation graphics

1) MS-Word
2) WingZ
3) MS-Excel

Consider the following three graphics created totally within MS-WORD

Figure 5 Areas of employment of reporting computer science graduates


Figure 6 Median salary of reporting UW-P computer science graduates


Figure 7 GPA distribution of students enrolled in CS courses


  • How were these built?
    • Demonstrate Chart Tool
  • Consider the WingZ Tour
    • Demonstrate
