*
|

* PURPOSE:
|
||||
*
|
||||
* Demonstrate how to use conference bridge.
|
||||
*
|
||||
* USAGE:
|
||||
*
|
||||
* confsample [file1.wav] [file2.wav] ...
|
||||
*
|
||||
* where:
|
||||
* fileN.wav are optional WAV files to be connected to the conference
|
||||
* bridge. The WAV files MUST have single channel (mono) and 16 bit PCM
|
||||
* samples. It can have arbitrary sampling rate.
|
||||
*
|
||||
* DESCRIPTION:
|
||||
*
|
||||
* Here we create a conference bridge, with at least two ports:
|
||||
* - port zero is for the sound device (capture and play),
|
||||
* - port one is to play a generated sine wave.
|
||||
*
|
||||
* If WAV files are specified, the WAV file player ports will be connected
|
||||
* to slot starting from number two in the bridge. The WAV files can have
|
||||
* arbitrary sampling rate; the bridge will convert the samples to its clock
|
||||
* rate. However, the files MUST have a single audio channel only (i.e. mono).
