Three main types of audio:
- Voice Over (VO)
- (Theme) Music
- Special Effects
Used to enhance the multimedia experience
Three things contribute to the size of an audio file. These can me
modified to reduce the size of the file, if necessary.
- Sample Rate- measured in Hertz, it is how often does the computer get a
"snapshot" of the audio
- Sample (bit) Depth – 8 or 16 bits. How many variations of loudness
can exist within the audio file
- Channels – Typically 1 (mono) or 2(stereo – Left and Right which can be
independent of each other)
Size of video depends on resolution on the screen (how big is it on the
screen), playback rate and compression used.
Frame rate is important also
