<p>A system for generating parametric output directly from a prerecorded and error corrected parametric signal (80) for playback in a parametric loudspeaker system. The method includes the step of retrieving a pre-encoded audio signal (80) from an electronically readable storage medium (70). In addition, an ultrasonic carrier signal has at least one sideband which represents the pre-encoded audio signal (80). The next step is playing back the pre-encoded audio signal through an ultrasonic amplifier (90) and emitter (100).</p> |
