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: In accordance with an embodiment, described herein are systems and methods for generation or selection of advertisement content or creatives (dynamic advertisements), in real-time, for use with a digital media content environment and media content streams. A media server enables streaming of media content to client media devices. An advertisement generation service can receive data or information describing, for example, a user profile associated with a user, to determine demographic data or information, and/or a metadata describing the media content played by the user within a current streaming session, and generate or select, in real-time, a dynamic advertisement for use with the streaming session. A dynamic advertisement can include a combination of background audio content (a background track), with voiceover audio content (a voiceover track), which is determined to be suitable in music style for playing within the current streaming session and/or to target the user's demographic data or information.

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: Systems, devices, apparatuses, components, methods, and techniques for automatically generating media previews are provided. An example media system for automatically generating media previews for a particular artist include a trailer generation application configured to receive input specifying an artist and duration of a trailer, automatically select clips from two or more media items by the artist, and automatically arrange and combine the clips into a media trailer for later playback.

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.

Abstract: A media content item sequencing system determines a sequence for playback of selected media content items, such as media content items in a playlist. The system calculates similarities between all possible pairs of the media content items and determines a sequence of the media content items using the similarities. The sequence of media content items can be determined by modeling the track features of the media content items with a graphic traversal problem and calculating a solution to the problem with various methods.

Abstract: A system of playing media content items determines transitions between pairs of media content items by determining desirable locations in which transitions across the pairs of media content items occur. The system uses a plurality of track features of media content items and determines such track features of each media content item associated with each of transition point candidates, such as beat positions, of that media content item. The system determines similarity in the plurality of track features between the transition point candidates of a first media content item and the transition point candidates for a second media content item being played subsequent to the first media content item. The transition points or portions of the first and second media content items are selected from the transition point candidates for the first and second media content items based on the similarity results.
