Abstract
Distortion free stitching of two temporally adjacent digital media files of any format or origin is described. Two digital media files are selected and placed temporally adjacent to each other. A determination is then made of the direction of each of the waveforms and an associated delta value between a last audio sample of a first to be played media file and a first audio sample of a next to be played media file. A stitching operation is performed, or not, based upon the respective directions of the waveforms and the associated delta value.

A method of distortion free stitching a digitally encoded track A waveform and a digitally encoded track B waveform at a transition point T, comprising;
- determining a direction of the track A waveform and the track B waveform;
- determining a delta value between a last audio sample of the track A waveform and a first audio sample of the track B waveform;
- and
- stitching the track A waveform and the track B waveform together based upon the directions of the tracks A and B and the associated delta value.
Computer program product executable by a processor for distortion free stitching a digitally encoded track A waveform and a digitally encoded track B waveform at a transition point T, comprising;
- computer code for determining a direction of the track A waveform and the track B waveform;
- computer code for determining a delta value between a last audio sample of the track A waveform and a first audio sample of the track B waveform;
- computer code for stitching the track A waveform and the track B waveform together based upon the directions of the tracks A and B and the associated delta value;
- and
- computer readable medium for storing the computer code.
