Systems and methods for providing real-time audio and data
A computerized method of delivering data to one or more client computing devices includes receiving, by a server computing device, a data stream starting at a first time; processing, by the server computing device, the data stream, thereby creating a processed data stream; transmitting, by the server computing device, via a wireless network in electronic communication with the server computing device, the processed data stream to the one or more client computing devices; and interpreting, by an application installed on the one or more client computing devices, the processed data stream, thereby recovering the data stream for use by the one or more client computing devices. A latency between the first time and the second time is less than 100 milliseconds.
1. A method of minimizing total latency of streaming a live data stream produced by a streaming data system while preserving continuity of the live data stream, the method comprising streaming a received live data stream over a wireless network between a server and a user listening device coupled to a smartphone and individually minimizing a latency of each of the following streaming data system components that are in a path of streaming of the received live data stream between the server and the user listening device:
the server's hardware interface;
the server's hardware interface driver;
a server application;
the server's network stack including a network hardware interface driver;
the server's network hardware interface;
an Ethernet network;
the wireless network's access port;
the wireless network;
the smartphone's hardware wireless network interface;
the smartphone's operating system network stack including a hardware wireless network interface driver;
a smartphone client application;
the smartphone's operating system; and
the smartphone's hardware interface coupled to the user listening device,
wherein a sum of latencies of each of the above streaming data system components from a first time of receiving the live data stream by the server's hardware interface to a second time of outputting the live data stream to the user listening device by the smartphone's hardware interface is less than 100 milliseconds.
2. The method of claim 1 , wherein the sum of latencies is less than 50 milliseconds.
