Abstract:

Described are a system and method for achieving near real-time musical collaboration by a group of users using computers connected by a network. Each computer system plays a stream of musical data to each user. The musical data stream played to each user corresponds to the musical collaboration produced by the users. The playing of the musical data streams is staggered such that each user is located at a different time in the musical collaboration than every other user. This staggering separates any two users by a temporal offset that exceeds the maximum time required to transmit musical data from one user to another user over the network. Each user is allowed to modify the portion of the musical data stream that is currently being played to that user. Such musical data modifications are transmitted to other users over the network to become incorporated into the musical data streams played to those other users. Because the musical data streams are staggered by a temporal offset that exceeds the maximum latency of the network, those other users to receive the musical data modifications with sufficient time to incorporate them into the locally played musical data streams.

International Classification:

G06T 1500

US Classification:

345419

Abstract:

A method for displaying musical data in three dimensions includes displaying musical data along a spatial path that does not lie within the image plane of a display. Graphical symbols corresponding to the musical data may be displayed on graphical surfaces aligned with the spatial path. The graphical surfaces form, in some embodiments, a tunnel through which the time axis associated with the musical data runs. The musical data may be manipulated to provide the viewer with the appearance of motion along the time axis associated with the musical data. In some embodiments, the viewer is represented by a virtual camera in the three-dimensional environment and the virtual camera is âmovedâ to provide the appearance of motion. A corresponding apparatus is also discussed.

US Classification:

463 7, 463 42, 84645

Abstract:

A method for providing real-time musical interaction among a plurality of players connected via a network includes the steps of analyzing local players musical performance to extract emulation data that represents the musical performance; transmitting emulation data to remote players over a network; receiving emulation data from remote players over the network; and using the emulation data to emulate the remote players musical performance by locally generating approximations of the performances.

International Classification:

US Classification:

Abstract:

In a music video game, a player's performance is digitally sampled while the player performs a musical composition. The player's performance is compared with a reference performance of the musical composition provided by the music video game. Performance feedback is presented to the player based on the results of the comparison. In some embodiments, sample times associated with digital samples of the player's live vocal performance are compared against timestamps of data records embedded or otherwise accompanying the reference performance audio track. Pitch and rhythm information is retrieved from the data record having a timestamp that most closely matches the sample time of interest. The pitch and rhythm data is used to compute pitch and rhythm errors, which are used to generate performance evaluation data. The performance evaluation data is used to present performance feedback to the player while the player is performing the musical composition.

Abstract:

An in-game interface for a music video game includes one or more feedback mechanisms configured to provide feedback to a player relating to the player's performance of the music video game. A compare module compares the player's performance with a reference performance provided by the music video game. A performance evaluation module determines the performance feedback to be presented to the player while the player performs the musical composition. In some embodiments, the player's pitch and rhythm are compared against a reference pitch and rhythm. If the player's pitch and rhythm matches the reference pitch and rhythm to within a predetermined target range, then the performance feedback is positive. Otherwise, the performance feedback is negative.
