Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.

Synchronizing playback by media playback devices

Techniques for shaping sound based on a speaker orientation are disclosed. In an embodiment, an audio data stream is obtained by a zone player having one or more speaker drivers, an orientation of the zone player is determined, and sound is reproduced by the zone player based on the orientation. The sound may be further shaped based on other states of the zone player in addition to orientation. The overall sound may be shaped from one zone player or from a collection of zone players.

Position-based playback of multichannel audio

Disclosed systems and methods include causing a graphical user interface to display an indication that a first and second playback device have been configured to play multi-channel audio content in at least one of a grouped mode or a stereo mode. Some embodiments include, (i) after receiving a command(s) to switch the first and second playback devices into the stereo mode while the first and second playback devices are in the grouped mode, configuring the first and second playback devices to play the multi-channel audio content in the stereo mode, and (ii) after receiving a command(s) to switch the first and second playback devices into the grouped mode while the first and second playback devices are in the stereo mode, configuring the first and second playback devices to play the multi-channel audio content in the grouped mode.

Playback device configuration and control

Disclosed embodiments include systems and methods for position-based playback of multichannel audio. Some embodiments include (i) determining first and second positions of first and second playback devices, respectively, (ii) receiving media content comprising multichannel content, (iii) generating first audio according to a first sound characteristic based on the received multichannel audio content and the first position of the first playback device, (iv) generating first audio according to a first sound characteristic based on the received multichannel audio content and the first position of the first playback device, and (v) causing synchronous playback of the generated first audio via the first playback device and the generated second audio via the second playback device.

Disclosed embodiments include systems and methods for position-based playback of multichannel audio. Some embodiments include (i) receiving, via a network interface of a first playback device, an indication of a position of a second playback device, (ii) determining, based on the received indication of the position of the second playback device, an audio characteristic of the first playback device, and (iii) playing back, via one or more transducers associated with the first playback device, a first portion of media content according to the determined audio characteristic in substantial synchrony with playback, via the second playback device, of a second portion of the media content.

Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. An example method includes receiving an audio signal containing a range of audio frequencies; amplifying, according to a gain parameter, the audio signal to be reproduced by at least one speaker. The example method includes automatically increasing the gain parameter to a higher gain parameter responsive to a determination that no more than a subset of the range of audio frequencies is to be reproduced by the at least one speaker. The example method includes amplifying, according to the higher gain parameter, the audio signal containing no more than the subset of the range of audio frequencies to be reproduced by the at least one speaker.

Playback device pairing

Systems, methods, and apparatus for frequency routing based on orientation are disclosed. An example method includes receiving, by a playback device, an audio data stream. The example method includes determining, by the playback device, an orientation of the playback device. The example method includes routing, by the playback device, a first set of frequencies in the audio data stream to at least one of a plurality of speaker drivers based on the first orientation. The example method includes routing, by the playback device, a second set of frequencies in the audio data stream to the at least one of the plurality of speaker drivers based on the second orientation, wherein the first set of frequencies is different than the second set of frequencies.

Frequency routing based on orientation

Certain embodiments provide methods and systems for managing a sound profile. An example playback device includes a network interface and a non-transitory computer readable storage medium having stored therein instructions executable by the processor. When executed by the processor, the instructions are to configure the playback device to receive, via the network interface over a local area network (LAN) from a controller device, an instruction. The example playback device is to obtain, based on the instruction, via the network interface from a location outside of the LAN, data comprising a sound profile. The example playback device is to update one or more parameters at the playback device based on the sound profile. The example playback device is to play back an audio signal according to the sound profile.

Adjusting a playback device

The present application discloses playback devices and networks, software for operating playback devices and playback device networks, and methods of operating playback devices and networks, where an individual network device is configured to switch between operating various operating modes comprising a non-paired mode and a paired mode, where the playback device is configured to output various channels of audio content within various audio frequency ranges while operating in the various operating modes.

An example method includes, based on an adjustment to a first displayed volume control, instructing the first playback device to adjust playback volume level; based on an adjustment to a second displayed volume control, instructing the second playback device to adjust playback volume level; after sending the commands, instructing the first and/or second playback device to process an audio stream into a first and/or second channel and to reproduce a respective one of the first and second channel, wherein the grouped first and second playback devices provide multi-channel sound; and based on an adjustment to a third displayed volume control, instructing the first and/or second playback device to adjust a group volume level for both the first and second playback devices.
