Abstract: Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. Particularly, the embodiments described herein enable two or more playback devices to be paired, such that multi-channel audio is achieved. Such embodiments may be used to produce stereo and multi-channel audio environments for television and movies.

Abstract: Methods and systems are provided for adjusting a crossover frequency between a plurality of audio speakers rendering audio content. In one example, a first subset of a plurality of audio speakers may be rendering a first sub-range of a range of audio frequencies of an audio content, and a second subset of speakers of the plurality of audio speakers may be rendering a second sub-range of the range of audio frequencies. In this example, the first sub-range and the second sub-range may be substantially separated at the crossover frequency. In one case, a playback volume at which the audio content is being rendered may be adjusted. In one instance, the crossover frequency may be adjusted in response to the volume adjustment to improve the audio content rendering quality by the respective subsets of audio speakers in the plurality of audio speakers.

Abstract: Systems, methods, apparatus, and articles of manufacture to provide automated configuration of local playback devices and networks based on external input are disclosed. An example media playback device includes a control interface to receive and process, at the media playback device, network configuration information for a local network from an external source, the control interface to receive and process the network configuration from the external source without requiring user intervention. The example media playback device includes a wireless interface to communicate with the local network based at least in part on the network configuration information. The example media playback device includes a speaker to output audio based on audio information received via the local network.

Abstract: Techniques for optimizing a player based on the addition of a second player are disclosed. In an embodiment, when a first player no longer needs to play certain audio frequencies due to the addition of a second player, the gain of the first player is automatically increased as part of the setup process. In another embodiment, when a first player needs to play certain audio frequencies, for example due to the removal of a second player, the gain of the first player is automatically decreased. Many other embodiments are disclosed.

Abstract: Techniques pertaining to enhancing acoustic effects of music playing through digital signal processing are disclosed. Genre, or style, of music embedded in a music file is received and identified in a digital signal processor (DSP). Based on the music genre, an equalization processing unit in the DSP processes the audio data stream in the music file through an equalization profile selected from a collection of sound equalization profiles preloaded in a memory unit. Each equalization profile contains digital algorithms specifically designed to boost or attenuate audio signals at certain frequency ranges in the audio frequency spectrum according to the characteristics of the style of the music. The equalization-processed audio data stream is then played in an audio playback system with an acoustic enhancement that closely reflects the nature and characteristics of the style of the music.

Abstract: Techniques for grouping or pairing individual audio products with network capability (players) to stimulate a multi-channel listening environment are disclosed. In instead of grouping selected players to play back an audio item, a user is allowed to activate one of the players to process the data of the audio item, essentially separating the data into individual streams, each of the streams representing a single-sound track and being played back in one of the players, thus creating a multi-channel listening environment with the selected players.

Abstract: 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.

Abstract: Certain embodiments provide methods and systems for managing a sound profile. An example method includes accessing a playback device on a network. The example method includes displaying a graphic interface to allow a user to adjust the sound profile, wherein the sound profile includes a plurality of parameters for user adjustment. The example method includes saving the sound profile. The example method includes processing an audio signal at the playback device according to the sound profile, wherein user adjustments to the sound profile are used to configure the playback device to process the audio signal upon saving the sound profile.
