Abstract: An excerpt of a media object is extracted by computing, for each bar of an N-bar loop, one or more perceptual quality vectors. For each of the one or more perceptual quality vectors within a search zone (S), one or more distances between bar i and bar i+N is computed and sorted to generate a sorted list of bars.

Abstract: A component for controlling playback of digital media objects using a single control input receives, from a server, a plurality of feature vectors, each feature vector representing one of a plurality of media objects, and receives one or more skip requests from the single control input. In response to a first skip request, the component selects a feature vector from among the plurality of feature vectors and instructs a media object playback device to playback a media object represented by the selected feature vector. In response to a second or successive skip request, the component selects another feature vector from among the plurality of feature vectors that is a distance away from the previously selected feature vector and instructs the media object playback device to playback another media object represented by the selected other feature vector.

Abstract: A media-playback device acquires a heart rate, selects a song with a first tempo, and initiates playback of the song. The song meets a set of qualification criteria and the first tempo is based on the heart rate, such as being equal to or less than the heart rate. The media-playback device also initiates playback of a binaural beat at a first frequency. Over a period of time, the binaural beat's first frequency is changed to a second frequency. Over the period of time, the first tempo can also be changed to a second tempo, where the second tempo is slower than the first tempo.

Abstract: A cuepoint determination system utilizes a convolutional neural network (CNN) to determine cuepoint placements within media content items to facilitate smooth transitions between them. For example, audio content from a media content item is normalized to a plurality of beats, the beats are partitioned into temporal sections, and acoustic feature groups are extracted from each beat in one or more of the temporal sections. The acoustic feature groups include at least downbeat confidence, position in bar, peak loudness, timbre and pitch. The extracted acoustic feature groups for each beat are provided as input to the CNN on a per temporal section basis to predict whether a beat immediately following the temporal section within the media content item is a candidate for cuepoint placement. A cuepoint placement is then determined from among the candidate cuepoint placements predicted by the CNN.

Abstract: This disclosure concerns the providing of media, and more particularly to the streaming of media. In one example embodiment of a method for streaming an audio content item to an electronic device, the method comprises: receiving a first data message comprising instructions from an electronic device to return a preview segment associated with a selected audio content item, the preview segment being a portion of the selected audio content item; retrieving said selected audio content item from a first storage; analyzing audio content of the retrieved audio content item to locate a portion of the selected audio content item to be used as the preview segment; extracting the located portion of the selected audio content item from the retrieved audio content item; and transmitting the extracted portion of the selected audio content item unencrypted to the electronic device.

Abstract: A system for playing media content items operates to provide smooth transitions between the media content items to continuously support a user's repetitive motion activity. The system can generate crossfade data containing information for transitions between media content items. The mix-in and mix-out points for the transitions are calculated to eliminate one or more portions of media content items that have lower musical energy than a majority portion of the items, and to maintain substantially consistent and/or stable musical energy (e.g., audio power or sound power) throughout the media content items including transitions therebetween.

Abstract: Methods, systems and computer program products are provided for identifying an audio stem. Audio stems (t1, . . . , tN) are stored on a stem database and songs (S1, . . . , SP) made with at least a subset of the plurality of the audio stems (t1, . . . , tN) are stored on a song database. At least partially composed song (S*) having a predetermined number of pre-selected stems (k) are received. In turn, a probability vector (or relevance value or ranking) is produced for each stem (t1, . . . , tN) to be complementary to the at least partially composed song (S*).

Abstract: A media system includes: a media-playback device including: a media-output device that plays media content items; and a tempo control engine to: select media content based upon suitability for a repetitive-motion activity; place each media content item from the media content into two or more pools of media content, with a first pool including media content which the user has previously indicated as being relevant, and a second pool including media content that the user has not previously indicated as being relevant; and sort the media content in each of the first pool and the second pool based upon tempo.
