Abstract: A device called a “Network Radio” for selecting, listening, and broadcasting real-time audio content and content in digital format to assist or enhance the real-time audio content; and a system comprising of the Network Radio, a wireless radio frequency network (cell/wi-fi), and a computer server or servers for managing, receiving and transmitting real-time content. After a station is selected, if the Network Radio's current function is for listening, the server initiates a real-time transmission of the requested audio. Once the device receives the transmitted audio it may process the real-time broadcast for better quality sound or decoding and for immediate audio output to the amplifier and speaker for the listener. If the device's current function is for broadcasting, then the device transmits the audio through the network to the server and the server initiates transmission to other devices whose current function is for listening and have requested the broadcasting station.
