Summary and Future Directions

We presented an enhancement to the DUET system in the form of a new demixing algorithm. The new approach uses delay and scale subtraction scoring (DASSS) to determine the active source(s) in a particular bin of a particular frame. We considered the role of the new scoring approach on determining the number of sources present in a given bin of a frame, and described related problems. We outlined a future approach for demixing multiple sources in such cases, and highlighted that the new approach benefits from the DASSS technique. In the near future, we will formalize the decision process about which two sources are present in the two source case. We will also develop the algorithm that allows sources to be considered only when they fit the harmonics plus noise model.
