  1. Audio

  2. MIDI vs. Digital Audio MIDI : shorthand representations of music stored in numeric form -- a “score” device dependent takes less memory is “vector drawing” of sound

  3. MIDI vs. Digital Audio Digital : the actual recording or “sampling” of the sound; not as device dependent takes more memory is “bitmap” of sound

  4. Audio Formats Most popular digital formats for web pages are: WAVE (Waveform Audio File Format) invented for Windows AU (Audio File Format) invented by Apple for Mac platform

  5. Audio on Composer Sound files in the following formats are recognizable: WAVE (“wav”) AU (“au”) MIDI (“midi” or “mid”)

  6. Audio on Composer Sound can only to be added to a web page using the HTML <EMBED> tag* <EMBED=“xfiles.wav”> * The <BGSOUND> tag is only supported by Explorer

  7. Audio on Composer Other attributes that can be used are: <EMBED=“xfiles.wav” HIDDEN=“true”> Hides sound player controls (“false” makes visible) <EMBED=“xfiles.wav” AUTOSTART=“true”> Sound loads automatically upon loading (“false” means it does not)

  8. Audio on Composer <EMBED=“xfiles.wav” LOOP=“true”> Specifies sound to be played continuously (“false” = not repeated; “n” = specified number) <EMBED=“xfiles.wav” VOLUME=“50” HEIGHT= “60” WIDTH=“144”> Provides settings for Player; this height and width expose Player completely.
