Abstract: An on-request wireless audio data streaming system is configured for providing on-request wireless audio data streaming to one or more wireless device apps on one or more wireless devices. The system comprises a directory server, audio capture interfaces and a wireless interface. The directory server coordinates the various components of the system. The audio capture interface obtains audio signals from sources of audio signals. The directory server maintains a list of available audio signals and broadcasts the list via the wireless interface. Wireless device apps receive the list, present it to their users. A user can select one of the available audio signals and request a subscription to it. The directory server maintains a list of the subscribed audio signals and associated subscribers. The audio capture interfaces generate and transmit via the wireless interface the audio data streams of the subscribed audio signals.
