Techniques have been developed to facilitate (1) the capture and pitch correction of vocal performances on handheld or other portable computing devices and (2) the mixing of such pitch-corrected vocal performances with backing tracks for audible rendering on targets that include such portable computing devices and as well as desktops, workstations, gaming stations, even telephony targets. Implementations of the described techniques employ signal processing techniques and allocations of system functionality that are suitable given the generally limited capabilities of such handheld or portable computing devices and that facilitate efficient encoding and communication of the pitch-corrected vocal performances (or precursors or derivatives thereof) via wireless and/or wired bandwidth-limited networks for rendering on portable computing devices or other targets.

A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

Provided is a radio client terminal such that a license for music distribution in a radio system is not required and such that music matching the preferences of the user can be played back at the appropriate times while audio content from a radio broadcast is being received and played back. The radio client terminal is configured so that music stored in advance in the storage unit of the radio client terminal according to the preferences of the user is played back after introductory audio from introductory audio content is output during the interval between playback of audio content and audio content.

Management device for a network of audiovisual information reproduction systems or jukeboxes, including a database with a plurality of sets of arrays, each array containing grouped information either about the composition of a jukebox, or the use of the jukebox, or the payment of fees. The database is managed by a computer server connected with the audiovisual information reproduction systems to receive messages sent by each audiovisual information reproduction device and containing information necessary to update determined sets of arrays in the database, and update data or the program for each audiovisual information reproduction device with information stored in at least one set of arrays in the database and transmitted in this message.

Systems and methods are presented for efficient cross-fading of compressed domain information streams on a user/client device. Exemplary systems may provide cross-fade between AAC/Enhanced AAC Plus information streams, between MP3 information streams, or between information streams of unmatched formats. These systems are distinguished in that cross-fade is directly applied to compressed bitstreams so a single decode operation is performed on the resulting bitstream. Thus, a set of frames from each input stream associated with the time interval in which a cross fade is decoded, and combined and recoded with a cross fade or other effect now in the compressed bitstream. Once sent through the client device's decoder, the user hears the transitional effect. The only input data that is decoded and processed is that associated with the portion of each stream used the crossfade, blend or other interstitial, and thus the vast majority of input streams are left compressed.

Techniques are disclosed relating to automatically generating new music content based on image representations of audio files. A music generation system includes a music generation subsystem and a music classification subsystem. The music generation subsystem may generate output music content according to music parameters that define policy for generating music. The classification subsystem may be used to classify whether music is generated by the music generation subsystem or is professionally produced music content. The music generation subsystem may implement an algorithm that is reinforced by prediction output from the music classification subsystem. Reinforcement may include tuning the music parameters to generate more human-like music content.

Techniques have been developed to facilitate the capture of performances on handheld or other portable computing devices and, in some cases, the pitch-correction and mixing of such vocal performances with backing tracks for audible rendering on such devices. Captivating visual animations and/or facilities for listener comment and ranking are provided in association with an audible rendering of a performance, e.g., a vocal performance captured and pitch-corrected at another similarly configured mobile device and mixed with backing instrumentals and/or vocals. Geocoding of captured vocal performances and/or listener feedback may facilitate animations or display artifacts in ways that are suggestive of a performance or endorsement emanating from a particular geographic locale on a user manipulable globe. In this way, implementations of the described functionality can transform otherwise mundane mobile devices into social instruments that foster a unique sense of global connectivity and community.
