Systems, devices, and methods for identifying media content using indirect qualities are provided. An example media-delivery system includes a content identification engine that applies a model associated with an indirect quality to media content items to generate indirect quality scores for the media content items, filters the media content items based on metadata associated with the media content items to generate filtered media content items, and presents at least some of the filtered media content items based on the indirect quality scores. An example media-playback device includes a search control engine that presents a search interface with a user-actuatable control for specifying a value of an indirect quality for use as a search criteria, transmits the search criteria to a media-delivery service, and receives media content items matching the search criteria from the media-delivery service, wherein the media content items are identified using a statistical model.

Identifying media content

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.

Search media content based upon tempo

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.

System for managing transitions between media content items

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.

Transitions between media content items

Computer systems and methods are provided for processing audio queries. An electronic device receives an audio clip and performs a matching process on the audio clip. The matching process includes comparing at least a portion of the audio clip to a plurality of reference audio tracks and identifying, based on the comparing, a first portion of a particular reference track that corresponds to the audio sample. Upon identifying the matching portion, the electronic device provides a backing track for playback which corresponds to the particular reference track, and an initial playback position of the backing track.

Karaoke query processing system

A system, method and computer product for extracting an activity from recordings. The method comprises searching for signals representing plural versions of a track, determining feature representations of the plural versions of the track identified in the searching, aligning the feature representations determined in the determining, and extracting a time varying activity signal from the feature representations aligned in the aligning.

Extracting signals from paired recordings

A system, method and computer product for predicting a content attribute are provided by collecting labeled media objects labeled with one or more attributes, constructing a feature vector of content-derived values for each of the labeled media objects, generating a model based on the feature vector and the one or more attributes, and applying the model to one or more unlabeled media objects to generate one or more attribute labels.

Automatic prediction of acoustic attributes from an audio signal

Systems, devices, apparatuses, components, methods, and techniques for identifying media content for playback during a repetitive motion activity are provided. An example media-playback device includes a media-output device that plays media content items and a repetitive-motion activity content identification engine. The repetitive-motion activity content identification engine is configured to: review media content items to identify the media content items that are conducive to performing repetitive-motion activities; and select certain media content items from the media content items, the certain media content items being conducive to performing the repetitive-motion activities.
