Overview of the proposed method. Gray-shaded areas are the extensions proposed in this paper. The signal-flow path starts with the microphone signals and continues through the pre-processing followed by the main processing and is completed with the calculation of a two-dimensional pattern ρ(φ,f0) in the post-processing. A particle filter is used on this 2D pattern to determine the DOA and pitch estimate.
