Abstract: A program product, a graphical user interface, a computer system including such a graphical user interface and method for replacing a first version of an audio and/or video section having a first length by selecting a second version of an audio and/or video section having a second length are described. Such a method comprises selecting the first version having the first length, displaying a first indication showing that the first version is selected, opening a menu associated with the first version offering at least the second version as an alternative to replace the first version, selecting the second version in the menu to replace the first version and displaying a second indication showing that the second version is selected. The second indication replaces the first indication. Some implementations may facilitate replacing one section or piece of audio or video data by another.

Abstract: A method to process digital audio data displays the digital audio data in one or more tracks along a time line in a graphical interface of a computer system and defines arrange regions within the time line of the digital audio data as objects for manipulation. Tracks within a selected arrange region are processed as an entity in accordance with commands received through the graphical user interface.

Abstract: The invention relates to systems, methods, and apparatus for assessing a musical performance. The musical performance can include a user's performance of a musical instrument. MIDI or audio notes are input and compared to the notes of a music track. An indication is provided to assess the musical performance. The assessment can be on the basis of timing and/or pitch errors.

Abstract: A song audio is played and a graphical representation of a musical instrument contributing to the audio is displayed. A fingering display is overlayed on the graphical representation of the instrument during the playing of song. The fingering display is synchronized to the song audio. During the playing of the song audio, the tempo of the song is adjusted. The pitch of the song is substantially preserved in real-time despite the tempo adjustment. In addition, the synchronization between the fingering display and the audio are maintained in real-time in view of the adjusted tempo.

Abstract: A technique for authoring multimedia presentations is provided such that a user may specify visual data to be displayed during the entirety of the playback of the presentation except for portions that have been defined to display alternate visual data. The authoring workflow utilizes a timeline within which may be placed marker regions with several independently editable parameters.
