摘要： A graphical user interface for music creation applications, such as score notation applications and digital audio workstations, includes multi-dimensional gestures. To enter a sound event into a musical project, a user uses an input device to select and drag a desired sound event in one or more dimensions. The relative position or rate of movement along a given dimension defines a value of a sound event parameter allocated to the given dimension. The sound event is entered into the project when the selection is released. The user inputs the gesture using a pointing device such as a mouse, stylus with a touch screen, or finger on a touch screen. Stylus dimensions mapped to sound event parameters may include, horizontal and vertical stylus tip positions, vertical and horizontal tilt of the stylus, and stylus tip pressure. Sound event parameters controlled by the gestures may include diatonic pitch, chromatic inflection, and duration.

摘要： An overlay surface for a user interface of a device comprises a lower light-diffusing semitransparent layer affixed to an upper transparent layer. Graphics printed on the bottom surface of the transparent layer are protected from wear by the overlying transparent layer, while light sources back-illuminating the graphics from below are diffused by the semitransparent layer before they reach the graphics. The graphics of the surface may be provided by an opaque mask having transparent or translucent cutouts. The multilayer surface enables the graphics to be evenly back-illuminated while at the same time being protected from external wear without the need for additional light-diffusing elements such as light pipes.

摘要： Tagged sound file libraries are searched using an iterative search application. A searcher specifies a multi-term search query which is directed to the sound libraries. Responsive audio files from the libraries are ranked by confidence levels for the occurrence of sounds corresponding to searched terms, weighted by user-determined search term priorities. High-ranking candidate audio files are presented to the user who is able to indicate a preference or a disfavoring of the candidates. Based on the feedback, the application adjusts the priorities of the individual search terms in the search query, adds or removes search terms from the query, and performs a new search with a revised set of search terms. The results are ranked using the adjusted priorities. The iterative search locates files with desired sounds that conform to the initial search or that have evolved from it under the user's direction.

摘要： Playback of a graphical representation of a digital musical score is synchronized with an expressive audio rendering of the score that contains tempo and dynamics beyond those specified in the score. The method involves determining a set of offsets for occurrences of score events in the audio rendering by comparing and temporally aligning audio waveforms of successive subclips of the audio rendering with corresponding audio waveforms of successive subclips of an audio rendering synthesized directly from the score. Tempos and dynamics of human performances may be extracted and used to generate expressive renderings synthesized from the corresponding digital score. This enables parties who wish to distribute or share music scores, such as composers and publishers, to allow prospective licensors to evaluate the score by listening to an expressive musical recording instead of a mechanically synthesized rendering.

摘要： A media file indexing service involves maintaining a media file index in a location external to the media file itself. The index is built up incrementally as the media file is being captured or transferred to shared storage. Client systems receive raw messages with information as to the location within the media file of media elements within each media file portion after it is written to shared storage, or receive refined messages indicating changes to the media file without the associated location information. Clients may query the index maintained by the index service for specific media elements during file capture, enabling edit-while-capture workflows.

摘要： A unique material identifier (UMID) for a media file that was not provided with a UMID at its point of origination is generated by using the content of the file, and is independent of the time of file import or accessing. For a given item of media material, the UMID remains unchanged and uniquely identifies the item when such a file is imported or accessed multiple times. The UMID may be generated by hashing together selected portions of the metadata and essence of the media file. The amount of metadata and essence sampled is chosen to provide a high degree of assurance that the UMID will be unique, but is kept small enough so as to avoid causing a perceptible lag when the UMID is generated. In various embodiments the UMID is based purely on one or more selected portions of the media file essence.

摘要： Synchronous playback of time-based media received from one or more locations remote from a primary editing/mixing studio is achieved by time-stamping media samples with a local presentation time before streaming them to the primary studio. At the primary studio, samples having the same presentation timestamp are played back at the same time, independently of the samples' arrival time at the playback system. Media stored locally to the playback system may also be included as part of the synchronous playback using locally computed presentation times. In order to accommodate media streaming transmission delays, the playback system negotiates a suitable delay with the remote systems such that samples corresponding to a given presentation time are received at the playback system from remote locations prior to playback of media corresponding to the given presentation time.

摘要： During the production of a time-based media project, it is often desirable for editors to work with media files or reels of a given size, both in terms of the temporal duration of media represented in each file and the number of tracks in a file. During the course of editing, files may become longer, or incorporate additional tracks, making them cumbersome to handle. A super-file view that displays multiple files simultaneously provides a framework for an editor to rebalance files during the course of media production. A graphical user interface permits users to adjust the content of the various files, including moving tracks among multiple files that comprise a given reel, as well as media between files belonging to different reels.

摘要： Methods and systems for populating a cache memory that services a media composition system. Caching priorities are based on a state of the media composition system, such as media currently within a media composition timeline, a composition playback location, media playback history, and temporal location within clips that are included in the composition. Caching may also be informed by descriptive metadata and media search results within a media composition client or a within a media asset management system accessed by the client. Additional caching priorities may be based on a project workflow phase or a client project schedule. Media may be partially written to or read from cache in order to meet media request deadlines. Caches may be local to a media composition system or remote, and may be fixed or portable.
