This is just a test for Spectrum Lab's built in HTTP server. To see it in action, do not load it as a file with your browser !
Instead, enable the server inside SpecLab, then enter the IP address of the machine on which SL is running.

Example (for the local network, not WWW): http://127.0.0.1/audiostream.html

Note: If the audio player appears (above), but doesn't start playing when hitting the 'play'-button, the Audio Streaming Server in Spectrum Lab may be disabled, while only the basic HTTP Server is active. How to turn on the audio streaming server is decribed here (online).
