ABSTRACT:
A system and method for use in a digitized audio data editing system for efficiently resequencing the audio data having indexes thereto. During resequencing, an audio index range table of such indexes is constructed. The table provides indications of consecutive index ranges of previously processed indexes. By traversing the table during resequencing to determine if a current index is a duplicate of any previously processed index corresponding to a previously copied audio segment, the necessity to compare each index with every index previously copied over is thereby avoided, which otherwise becomes increasingly inefficient as more indexes are copied over and thus the number of indexes to compare expands. Time required to process a resequence is accordingly significantly reduced.
