A method of buffering audio data in an audio playback system that is adapted to receive and playback separate, discrete audio files from one or more audio sources, where the audio files comprise audio data, and where the audio playback system comprises a master device that receives audio files from a source, buffers the received audio data, and distributes the buffered audio data to one or more active slave audio playback devices. The master device requests a first audio file from an audio source, receives the first audio file, buffers audio data from the first audio file, and sends buffered audio data from the first audio file to one or more active slave audio playback devices. During playback of the audio data from the first audio file, the master device requests a second audio file from an audio source, receives the second audio file, buffers audio data from the second audio file, and sends buffered audio data from the second audio file to one or more active slave audio playback devices.

Audio data buffering

A software tool includes a plurality of pre-coded API sensor modules for obtaining information from the sensors coupled to a mobile device and a pre-coded API audio module for playing audio content based on the information obtained from at least one of the sensors.

Augmented reality software development kit

A method for implementing a user interface (UI) control in a networked audio system that includes a plurality of audio playback devices that are adapted to play audio and that are operatively connected to a network over which audio data is delivered from a digital audio source to the audio playback devices, where the networked audio system further includes a control device that is operatively connected to the network and that has a display that is adapted to display a representation of a UI, and where the control device comprises an operating system (OS) and a native application program written for the control device OS, and memory. There is a local UI program that is stored in the control device memory. The local UI program is loaded in the control device when the native application is opened. The loaded UI is then displayed on the control device display.

User interface control in a networked audio system

A method of synchronizing playback of audio over a plurality of wireless speaker packages that are each adapted to play audio, where the audio comprises a plurality of frames of encoded audio data. The method includes determining an offset time of a frame of encoded audio data, where the offset time corresponds to the time when the frame playback is to begin, and inserting the determined offset time into the frame of encoded audio data.

Encoded audio synchronization

Aspects of the present disclosure provide a first apparatus configured to transmit a first signal having a first frequency to a second apparatus, receive, from the second apparatus, a second signal having a second frequency responsive to the first signal, determine a latency associated with the transmitted first signal and received second signal and, determine a distance between the first apparatus and the second apparatus based, at least in part, on the determined latencies. According to an example, the first apparatus further determines a direction of the second apparatus relative to the first apparatus. According to an example, at least one of the first signal or second signal comprises an ultrasonic or high-frequency signal.

Determining location/orientation of an audio device

A method and device for synchronously playing audio data over a number of audio playback devices that are connected to a network. The distribution of particular audio data to a plurality of audio playback devices that are adapted to play audio, where the audio playback devices are all connected to a network over which audio data is delivered from a digital audio source to the audio playback devices, can be accomplished by determining when more than one of the audio playback devices has been directed to play the particular audio data, and in response to the determination directing that two or more of the audio playback devices synchronously play the particular audio data.

Synchronous audio playback

A method and device for distributing audio data to a number of audio playback devices that are connected to a network. One or more network-related performance criteria of a plurality of the audio playback devices are compared. Based on the comparison, at least one of the audio playback devices is designated as a master device and at least one other of the audio playback devices is designated as a slave device. The master device then controls the distribution of audio data to one or more of the slave devices.
