<p>An audio speed converter provides audio speed changes without loosing relevant information, and is suitable for use with video systems so as to provide better synchronization between output audio and video signals. According to an exemplary embodiment, a system for processing an audio signal includes a first processor for receiving the audio signal at a first rate of speed, and processing the received audio signal in dependence upon a plurality of control signals. Each of the control signals represents a level of a different reference parameter. The first processor provides output of the received audio signal at a second rate of speed in dependence upon the processing. A speed rate comparator compares the second rate of speed to a required rate of speed, and generates a comparison signal in dependence upon the comparison. A second processor generates the control signals in dependence upon the comparison signal.</p> |
