摘要:
An apparatus and method for generating 3D graphics objects utilizes algorithms to generate the objects when driven by audio events. In one embodiment a “hydra” object has branches that are recursively generated. Parameters used to algorithmically generate the object are controlled by a control signal driven by detected events in an audio signal. Additional algorithms include a phase plot using audio parameters. A generalized system includes an audio analysis block for generating audio control signals utilized by object generation, objects selection and object placement blocks to generate 3D objects.

A method and system to drive transformations of a visual representation, in real-time, that synchronizes the audio and visual outputs and controls the magnitude of object deformation to be visual pleasing. In one embodiment, sudden increases in the spectral energy are detected to time the initialization of deformations and a smoothed signal is derived from the time varying spectral energy curve to control the magnitude of the deformations.

A technique for enhancing an audio-driven computer generated animation includes the step of mapping a video clip generated by a digital camera to an object displayed in the animation. Additionally, the object or the video clip can be deformed when selected events are detected during playback of the video clip.

A technique for changing the appearance of visual images mapped on a 3D object rendered by a computer includes the stepped of remapping texture coordinates to vertices of a 3D object at discrete time intervals and blending the remapped images. The control intervals are triggered by events in monitored signal such as an audio feed or a video stream. The images of the video stream can be the textures mapped to the 3D object.

A method and device for facilitating navigation of digital media to a user are provided. A digital media player, or (“client”) has access to a plurality of digital media records, e.g., a library of digitized musical performances that may be stored in a memory of the device. The client may have access to electronic digital media documents stored in additional devices or memories, and/or via an electronic communications network to a data warehouse. The client enables a user to select an electronic document for playing on the client from a plurality of electronic documents. The client presents two or more visual images to the user, wherein each visual image represents a discrete electronic digital document, e.g., a CD jewelcase or a DVD package. The software directs the user to select a visual image, in which the images that are subsequently presented to the user may depend upon previous user selections.

A system (200) for processing a sound signal (212) that allows dynamic customization of perceived spatial positions and sound qualities of sound components associated with the sound signal (212). The system provides apparatus for processing a sound signal (212) that includes an input to receive the sound signal (212), a sound unmixer (204) coupled to the input to receive the sound signal (212) and unmix at least one sound stream (216) from the sound signal (212) based on at least one unmixing instruction (214), and an output coupled to the sound unmixer (214) to output the at least one sound stream (216).
摘要:
A system and method for modifying a subportion of information contained in an audio, such as magnitude information, without substantially effecting the remaining information contained therein, such a phase information. An incoming audio signal is segmented into a sequence of overlapping windowed DFT representations, during an analysis step, and during a synthesis step the DFT representations are converted back to a time domain signal. Each of the DFT representations consists of a plurality of frequency components obtained during a period of time. Each of the frequency components is associated with a unique increment of the period. Subsequent to the analysis step, but before the synthesis step, the frequency components of the DFT representations are re-mapped so as to have a differing temporal relationship with respect to the increments of the period of time.
