Abstract: Systems, methods, apparatus, and articles of manufacture to provide for low-latency delivery and playback of audio are disclosed. In one embodiment, an example audio system includes multiple playback devices including a primary device and one or more secondary devices, whereby, the primary device establishes and controls a peer-to-peer network that connects, wirelessly or wired, to each of the satellite devices. An example audio device contains a channel selector, a control interface, and an audio interface. In some embodiments the control interface is used to transmit control information to another device on a first frequency channel, and the audio interface is used to transmit audio information to another device on a second frequency channel.

Abstract: Methods and apparatus for direction routing between nodes of networks are disclosed. An example method includes identifying a destination node of first data received at a first node; calculating a logical distance from the first node to the destination node; and, when the logical distance meets a threshold condition and when a direct route from the first node to the destination node is blocked according to a protocol setting, overriding the protocol setting to enable transmission of the first data from the first node to the destination node via the direct route.

Abstract: Systems, methods, apparatus, and articles of manufacture to control audio playback devices are disclosed. An example audio playback device includes an audio output device to generate audio signals based on a signal source, a device interface to receive a first message from a first audio information source, and a source selector to change the signal source from a second audio information source to the first audio information source based on the first message.
