A system () for processing a sound signal () that allows dynamic customization of perceived spatial positions and sound qualities of sound components associated with the sound signal (). The system provides apparatus for processing a sound signal () that includes an input to receive the sound signal (), a sound unmixer () coupled to the input to receive the sound signal () and unmix at least one sound stream () from the sound signal () based on at least one unmixing instruction (), and an output coupled to the sound unmixer () to output the at least one sound stream ().

Process for removing voice from stereo recordings

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.

Audio driven self-generating objects

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.

Automated acquisition of video textures acquired from a digital camera for mapping to audio-driven deformable objects

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.

Audio driven texture and color deformations of computer generated graphics

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.

Audio-driven visual representations

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.

Sound modification employing spectral warping techniques

A method and apparatus for vocally entering acoustic data and producing an output. In one embodiment, a note preset is identified and selected according to the vocal input signal, and auxiliary note information is also extracted from the vocal input signal. The auxiliary note information is used to generate synthesis engine parameters that modify the note preset to provide a complex note output. In another embodiment, feature vectors of note segments are used to select a preset file representing a particular instrument from a library of instrument preset files. A note preset is selected from the instrument preset file according to the note segment to create an output corresponding to the selected instrument or instrument group.
