* broadcaster supports receiving audio packets from multiple audio sources. Each audio packet's internal audio
* metadata source string is used to reassemble each packet stream. Recordings are capped at 30 seconds length.
* If a source audio packet stream exceeds 30 seconds in length, it will be chunked into 30 second recordings.
*
* This broadcaster supports a time delay setting for delaying broadcast of audio recordings. The delay setting is
* defined in the broadcast configuration. When this delay is greater than zero, the recording will remain in the
* audio broadcaster queue until the recording start time + delay elapses. Audio recordings are processed in a FIFO
* manner.
*
* Use the start() and stop() methods to connect to/disconnect from the remote server. Audio recordings will be
* streamed to the remote server when available. One second silence frames will be broadcast to the server when
* there are no recordings available, in order to maintain a connection with the remote server. Any audio packet
* streams received while the broadcaster is stopped will be ignored.
*
* The last audio packet's metadata is automatically attached to the closed audio recording when it is enqueued for
* broadcast. That metadata will be updated on the remote server once the audio recording is opened for streaming.
