A communication component modifies production of an audio waveform at determined modification segments to thereby mitigate the effects of a delay in processing and / or receiving a subsequent audio waveform. The audio waveform and / or data associated with the audio waveform are analyzed to identify the modification segments based on characteristics of the audio waveform and / or data associated therewith. The modification segments show where the production of the audio waveform may be modified without substantially affecting the clarity of the sound or audio. In one embodiment, the invention modifies the sound production at the identified modification segments to extend production time and thereby mitigate the effects of delay in receiving and / or processing a subsequent audio waveform for production.

A scheme for stereo and multi-channel synthesis of inter-channel correlation (ICC) (normalized cross-correlation) cues for parametric stereo and multi-channel coding. The scheme synthesizes ICC cues such that they approximate those of the original. For that purpose, diffuse audio channels are generated and mixed with the transmitted combined (e.g., sum) signal(s). The diffuse audio channels are preferably generated using relatively long filters with exponentially decaying Gaussian impulse responses. Such impulse responses generate diffuse sound similar to late reverberation. An alternative implementation for reduced computational complexity is proposed, where inter-channel level difference (ICLD), inter-channel time difference (ICTD), and ICC synthesis are all carried out in the domain of a single short-time Fourier transform (STFT), including the filtering for diffuse sound generation.

A system that includes a desk top assembly of a display and sensors mounted on a robotic arm. The arm moves the assembly so that it remains within position and orientation tolerances relative to the user's head as the user looks around. Near-field speaker arrays supply audio and a microphone array senses a user's voice. Filters are applied to head motion to reduce latency for arm's tracking of the head. The system is full duplex with other systems allowing immersive collaboration. Lighting and sound generation take place close to the user's head. A haptic interface device allows the user to grab the display / sensor array and move it about. Motion acts as a planar selection device for 3D data. Planar force feedback allows a user to “feel” the data. Users see not only each other through display windows, but can also see the positions and orientations of each others' planar selections of shared 3D models or data.
