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.

Claims

1. A digital audio workstation comprising:

a. means for storing digital audio information;

b. means for selecting a portion of digital audio information at audio sampling times spaced apart by less than one-thirtieth of a second;

c. a computer-readable randomly-accessible storage medium in which digital video information is stored and is associated in time with the digital audio information;

d. means for detecting selection by an operator of the portion of digital audio information; and

e. means for accessing the digital video information based on the selected portion of digital audio information selected by the operator.

2. The digital audio workstation of claim 1, wherein the accessed video information is from an identical time portion as the indicated audio information.

3. The workstation of claim 1, wherein the accessed video information is offset from the selected audio information by a particular time period indicated.

4. The workstation of claim 1, wherein the accessed video information is displayed essentially immediately upon the selection of the associated audio information.

5. The workstation of claim 1, further comprising means for displaying a visual timeline which represents waveforms of the audio information.

6. The workstation of claim 1, further comprising means for indicating segments of the digital audio information on a computer display and for allowing editing those segments by using computer user-interface techniques of cutting, pasting, and dragging.

7. The workstation of claim 1, further comprising a means for repeatedly playing a segment of the digital video information while allowing the operator to move the digital audio segment associated with that video segment forward or backward in time so as to synchronize events in the digital audio segment and the digital video information.

8. The workstation of claim 1, further comprising a means for repeatedly playing a segment of the digital video information while successively playing different versions of a segment of the digital audio information associated with the digital video information so as to enable the operator to choose one version of the digital audio segment.

9. The workstation of claim 1, further comprising a means for storing, in association with a particular point of the digital audio information, a digitized voice or textual message for later reference regarding the digital audio information.

10. The workstation of claim 1, further comprising a means for digitizing analog video information to produce the digital video information for storage.

11. The workstation of claim 10, wherein the accessed video information is from an identical time portion as the indicated audio information.

12. The workstation of claim 10, wherein the accessed video information is offset from the selected audio information by a particular time period indicated.

13. The workstation of claim 10, wherein the accessed video information is displayed essentially immediately upon the selection of the associated audio information.

14. The workstation of claim 10, further comprising means for displaying a visual timeline which represents waveforms of the audio information.

15. The workstation of claim 10, further comprising means for indicating segments of the digital audio information on a computer display and for allowing editing those segments by using computer user-interface techniques of cutting, pasting, and dragging.

16. The workstation of claim 10, further comprising a means for repeatedly playing a segment of the digital video information while allowing the operator to move the digital audio segment associated with that video segment forward or backward in time so as to synchronize events in the digital audio segment and the digital video information.

17. The workstation of claim 10, further comprising a means for repeatedly playing a segment of the digital video information while successively playing different versions of a segment of the digital audio information associated with the digital video information so as to enable the operator to choose one version of the digital audio segment.

18. The workstation of claim 10, further comprising a means for storing, in association with a particular point of the digital audio information, a digitized voice or textual message for later reference regarding the digital audio information.

19. A digital audio workstation comprising:

means for storing multiple tracks of digital audio information;

means for storing video information having frame rate and synchronized to said digital audio information in a storage medium that provides non-linear and random access to any selected portion of said video information;

means for selecting a portion of said multiple tracks of digital audio information at a resolution less than the frame rate of the video information; and

means for displaying portions of said video information associated with said digital audio information during editing of said digital audio information.

20. A digital audio workstation as defined in claim 19 wherein said means for selecting a portion of said multiple tracks of digital audio information includes means for editing said digital audio information at times corresponding to audio sampling boundaries.

21. A digital audio workstation as defined in claim 20 wherein said means for selecting a portion of said multiple tracks of digital audio information includes

means for generating a timeline display containing information representative of said multiple tracks of digital audio information in a selected clip;

means for displaying a list of available audio clips in a workreel; and

means for selecting audio clips in said workreel and transferring said audio clips from said workreel to said timeline to provide an edited clip in said timeline.

22. A digital audio workstation as defined in claim 21 further including means for controlling recording and playback of said digital audio information.

23. A digital audio workstation as defined in claim 21 further including means for associating locators representative of specific events with specific subframe locations in said digital audio information and means for accessing said specific subframe locations by selecting one of said locators.

24. A digital audio workstation as defined in claim 19 wherein said means for displaying portions of said video information includes means for repeatedly displaying a selected portion of said video information in a loop and wherein said means for selecting a portion of said multiple tracks of digital audio information includes means for recording digital audio information each time the selected portion of said video information is played.

25. A digital audio workstation as defined in claim 24 wherein said means for repeatedly displaying a selected portion of said video information in a loop includes means for automatically repeating said selected portion of video information after a predetermined delay.

26. A digital audio workstation as defined in claim 24 wherein said means for repeatedly displaying a selected portion of said video information in a loop includes means for displaying said selected portion of video information after manual initiation by a user.

27. A method for editing digital audio comprising the steps of:

storing multiple tracks of digital audio information;

storing video information having a frame rate and synchronized to said digital audio information in a storage medium that provides non-linear and random access to any selected portion of said video information;

selecting a portion of said multiple tracks of digital audio information at a resolution less than the frame rate of the video information; and

displaying portions of said video information associated with said digital audio information during editing of said digital audio information.
