Abstract: 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.

Abstract: Vocal musical performances may be captured and continuously pitch-corrected at a mobile device for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at the mobile device in accord with pitch correction settings. In some cases, such pitch correction settings code a particular key or scale for the vocal performance or for portions thereof. In some cases, pitch correction settings include a score-coded melody sequence of note targets supplied with, or for association with, the lyrics and/or backing track. In some cases, pitch correction settings are dynamically variable based on gestures captured at a user interface.

Abstract: Systems, methods and apparatus directed to a global metronome configured at each of one or more locations to receive a high accuracy timing signal and responsively update a local clock thereto, to determine a phase of a virtual metronome using the updated local clock, a predetermined epoch start time and a predetermined virtual metronome period, to phase synchronize a local metronome to the virtual metronome, and to control local devices providing audio playback and/or a sequence of nonmusical events in accordance with start/stop/tempo messages configured in accordance with the local metronome. By using the global metronome at each of a plurality of locations to synchronize/control devices at those locations, the local devices that each of the plurality of locations are inherently synchronized with each other.

Abstract: Techniques have been developed to facilitate the capture 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.

Abstract: A fingerprint and indexing service is implemented to receive a media object and generate a fingerprint corresponding to the media object. The fingerprint and indexing service may segment the fingerprint into frames and generate a confidence value for each bit within each frame. The confidence values may be added together and totaled, such that each frame has a corresponding confidence score. The frames may be ranked, according to their confidence scores. N of the top ranked frames may be selected as the index. Subsequently, a search component may determine the index values for a query media object. The database of media objects may be searched for matching index values for fingerprints with fingerprint lengths matching the query media object's length. Once a match is declared, the fingerprints of the query media object and the matching media objects within the database may be compared to determine if a match exists.

Abstract: Physical controls on a physical controller device (PCD) are dynamically mapped to application controls for an application being executed on a computer having a touch-sensitive display surface. The computer identifies a PCD which has been placed by a user on the display surface and displays a mapping aura for the PCD. When the user touches an activate direct-touch button displayed within the mapping aura, the computer activates a mapping procedure for the PCD and displays a highlighted direct-touch button over each application control which is available to be mapped to the physical controls on the PCD. When the user selects a particular application control which is available to be mapped by touching the highlighted button residing over the control, the computer creates a dynamic mapping between the selected application control and a user-selected physical control on the PCD.
