Streaming Audio (and video)

Popular new delivery medium for the Web and other Multimedia networks

Examples of streamed audio (and video) (and video)

• Real Audio
• Shockwave
• .wav files (not video obviously)

Here is an example of a real audio file recorded and produced for the Web by myself

• The file was originally recorded at CD Quality (44 Khz, 16-bit Stereo) and is nearly minutes in length.
• The original uncompressed file is about 80 Mb.
• The compressed file (at 33.3) is only 1.7 Mb in total and is still of very good quality.
• The file is downloaded to browser and not steamed above. Whilst real audio players and encoders are freely available ( see {\em http://www.realaudio.com/}). Real audio servers {\bf cost money}.

  • Buffered Data:
    • Trick get data to destination before it's needed
    • Temporarily store in memory (Buffer)
    • Server keeps feeding the buffer
    • Client Application reads buffer
  • Needs Reliable Connection, moderately fast too.
  • Specialised client, Steaming Audio Protocol (PNM for real audio).
