VIEWING AN EXISTING RECORDED SOUND AS A DIGITAL AUDIO FILE, SET HORIZONTAL UPPER AND LOWER LIMITS ON THE WAVEFORM‘S PEAKS AND TROUGHS RESPECTIVELY. THE MANIPULATED WAVEFORM IS CONSTRUCTED USING THE EFFECTIVE AREA ENCLOSED BY THE WAVEFORM AND THESE LIMIT LINES.

INSTEAD OF USING THE VERTICAL MEASUREMENT BETWEEN THE ‚ZERO‘ LINE AND ITS CORRESPONDING POINT IMMEDIATELY ABOVE OR BELOW AS THE AMPLITUDE READING. THE NEW WAVEFORM SHALL REVERSE THE DIRECTION OF THE AMPLITUDE READINGS TO CREATE ITS FORM. THUS FLIPPING EACH PEAK AND TROUGH ON ITS MID-POINT AXIS.

The text above describes how a new waveform is formally constructed from readings taken from the unused part of the original waveform.
