Abstract

A method and apparatus for marking audio data as it is recorded, and a user interface for the audio data in a computerized system, is disclosed. A recorder, such as a tape recorder, having a plurality of marker buttons is provided. The audio data is recorded on one channel of a magnetic tape. Any time one of the marker buttons is pressed, a distinct tone is recorded on another channel of the tape as a marker. The audio data and markers are then transferred to the computer system. The user interface provides a graphical display of the audio data, and provides graphical markers which correspond to the marker buttons on the recorder. The audio data can be accessed at any random point, including a point marked by a marker. Without changing modes, a user can access the data at any random point, stop play, select a new point to initiate playback and restart playback, and change the speed of playback. Additional functions, such as editing, zooming the display and changing the form of the graphical display, are also provided.

Claims

1. An audio data user interface for use in a computerized system having a processor, a memory and a display device comprising:

a visual representation of said audio data displayed on said display device by said processor, said memory storing information corresponding to said visual representation, wherein said visual representation is displayed along a first axis and a second axis, wherein a width of one of said first and said second axis varies as a magnification of said audio data shown by said visual representation varies.

2. The audio data user interface as described in claim 1 wherein said visual representation comprises a representation of an amplitude of said audio data, said visual representation comprising a color bar representation.

3. The audio data user interface as described in claim 2 wherein said amplitude is mapped to color saturation.

4. The audio data user interface as described in claim 3 wherein the other of said first and said second axis represents time.

5. The audio data user interface as described in claim 2 wherein the other of said first and said second axis represents time.

6. The audio data user interface as described in claim 1 wherein the other of said first and said second axis represents time.
