Abstract: Systems, devices, apparatuses, components, methods, and techniques for providing media content to a media playback system are provided. The techniques provide for determining whether a playback system is connected, or otherwise associated with, a playback device suitable for 3D audio playback. Upon determining that a playback system is or is not connected or otherwise associated with a playback device suitable for 3D audio playback, audio content in a corresponding format may then be transferred and/or played by a requesting system. In some examples, one or more filters may be applied to requested audio content to compensate for determined user head movement and/or to create simulated 3D audio from generic two-channel recording.

Abstract: A method comprises obtaining a playlist that comprises a plurality of audio items. The playlist is divided into a plurality of coherent groups. Each coherent group comprises a respective sequence of audio items of the plurality of audio items with a common attribute. For a respective coherent group of the plurality of coherent groups, a parameter value of a first audio item of the respective sequence is determined, a parameter value of a second audio item of the respective sequence is adjusted based on the determined parameter value of the first audio item, and a transition media item is formed. The transition media item corresponds to a transition between the first and second audio items that are adjacent in the respective sequence. The transition media item is provided to a second electronic device.

Abstract: A method comprises obtaining a playlist that comprises a plurality of audio items, and dividing the playlist into a plurality of coherent groups, wherein each coherent group comprises a respective sequence of audio items of the plurality of audio items with a common attribute. For a respective coherent group of the plurality of coherent groups, the method comprises determining a parameter value of a first audio item of the respective sequence and adjusting a parameter value of a second audio item of the respective sequence based on the determined parameter value of the first audio item, to form a transition between the first and second audio items. The first and second audio items are adjacent in the respective sequence. The transition is provided to a second electronic device for playback.
