Abstract: The invention disclosed herein is a digital audio workstation for the audio portions of video programs. It combines audio editing capability with the ability to immediately display video images associated with the audio program. The invention detects an operator's indication of a point or segment of audio information and uses it to retrieve and display the video images that correspond to the indicated audio programming. Another aspect of the invention is a labeling and notation system for recorded digitized audio or video information. The system provides a means of storing in association with a particular point of the audio or video information a digitized voice or textual message for later reference regarding that information.

Abstract: An improved CD transport apparatus wherein said apparatus incorporates a digital signal processor for processing digital audio signals read from a compact disc. The digital signal processor additionally serves to alter the gain of the digital audio signal when various control operations are commanded by the user so as to minimize audibility of extraneous noises which accompany such control operations and the potential damage which may be caused to audio components. The improved CD transport apparatus further includes a cueing switch for causing movement of the CD pickup only during movement of the cueing switch and a shuttle switch for causing movement of the CD pickup only when the shuttle switch is in an active position.

Abstract: A digital-to-analog converter--preamplifier apparatus serving as an interface between a source of digital audio signal data and an amplifier is disclosed. A digital stage receives multiple digital audio signal inputs, a selected one of which is analyzed by a digital audio interface receiver, processed by a digital signal processing device and a delta-sigma modulator prior to passing to the analog stage for conversion from the digital domain into left and right channel analog audio output signals. Volume control is performed on the audio signal in both the digital domain and the analog domain in order to optimize performance and minimize noise. The present invention automatically adjust for input word lengths of greater than 18-bits.

Abstract: A partition system comprising a fixed standard and upstanding acoustical panels, with brackets affixed to the standard for securement of the panels thereto and for support of shelves and desk tops adjacent the panels. Connecting hardware securing panels to the brackets and standard is hidden from view. Panel faces are covered with fabric sheets, and panel frames are formed with outwardly directed channels accommodating splines wedging perimetric edge portions of the fabric sheets therewithin.
