Radio (mp3)




missing image

This example is similar to soundSpace except Internet radio stations are attached to events rather than audio files. Audio hiding values are set on the categories to more rapidly reduce the volume when a category moves away from the center of the screen.

demonstrates:
  • a relative timeline
  • events defined with audio files
  • playing audio in the mp3 format
  • playing streaming audio
  • spatial location of audio
  • rapidly diminishing volume (hiding) as sound events move away from the center of the window (when the view direction is towards the past or future)
requires:
  • Working GStreamer support for mp3 files. This support is installed with Quotidian for Mac and Windows. GStreamer and mp3 support are installed separately on Linux.
  • a reasonably fast Internet connection to play the streaming audio without hesitation.
things to try:
  • Make sure that your machines's speakers are on, that the volume is set at an audible level and that the "play sounds" control missing image is active. You should hear water drops. The center event plays the same sound file played by the soundSpace example. The other events are defined with streams from Internet radio stations.
  • Unlike the soundSpace example, the categories in this example are defined so that there is very little overlap between neighboring sounds as the user moves between events
  • Move the x/y control (the square control) a small amount so that different events are gradually moved to the center of the window. Note how the radio stations change.
  • You can make a copy of this timeline file and use the Quotidian Editor to replace the sound links with the URLs of other Internet radio streams.
