    Abstract: Down scoring overcrowded bands via IDF weighting scores provides a soft way to reduce the effect of common bands from Locality Sensitive Hashing (LSH) processes. An index component indexes live video references of a live streaming infrastructure pathway process in a reference index. A scoring component scores a set of bands with a set of inverse document frequency (IDF) weighting scores in the reference index. A high score is generated for bands that are featured in a small number of references and a low score is generated for bands featured in a high number of references.

    Abstract: Systems and methods are provided herein relating to audio classification. Genres of music can be identified by detecting unique spectral features inherent to those genres. One example genre detected is techno music. Two dimensional discrete cosine transforms can be generated for consecutive windows of the spectrogram or chromagram. A max value of the energy of portions of the two dimensional discrete cosine transforms can be determined. The max value can be normalized and aggregated with max values related to neighboring windows. If the aggregate scores meet a genre threshold, the audio sample, or portions thereof, can be associated with a genre of music.

    Abstract: Systems and methods are provided herein relating to audio matching. Descriptors can be generated based on anchor points and interest points that characterize the local neighborhood surrounding the anchor point. Characterizing the local spectrogram neighborhood surrounding anchor points can be more robust to pitch shift distortions and time stretch distortions. Those anchor points surrounded by a lack of spectral activity or even spectral activity can be filtered from further examination. Using these pitch shift and time stretch resistant audio features within descriptors can provide for more accurate and efficient audio matching.

    Abstract: Systems and methods are provided herein relating to interactive gaming within a media sharing service. Game data, such as sets of notes extracted from the audio track of user generated videos or from audio samples, can be generated based on videos containing musical content or from audio content. A device can use the game data to facilitate an interactive game during playback of the user generated videos or audio samples. Players can press buttons, for example, corresponding to notes as the video with musical content is played within the game interface. Players can be scored for accuracy, and can play with other players in a multiplayer environment. In this sense, user generated video content or audio content can be transformed and used within a gaming interface to increase interaction and engagement between users in a media sharing service.
