An irrelevance algorithm based on simultaneous masking is implemented In STx. In the years following its first development by Eckel, the efficiency of this algorithm has been clearly shown. In this project, this irrelevance model will be based on modern mathematic and psychoacoustic theories and knowledge.
This algorithm can be described as a Gabor multiplier with an adaptive symbol. With existing related theory, it becomes clear that a high redundancy must be selected. This guarantees:
Furthermore, it can be shown that the model used for the spreading function here is mathematically equivalent to the excitation pattern.
This algorithm has been used for several years already for things such as:
