Which among the following is the first step in auditory scene analysis

1.	Which among the following is the first step in auditory scene analysis?(a) Pitch scale detection(b) Filtering(c) Grouping(d) SegmentationI have been asked this question at a job interview.Enquiry is from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio
Answer» CORRECT choice is (d) Segmentation Explanation: AUDITORY scene analysis consists of TWO steps namely segmentation and grouping. INITIALLY, the auditory scene is subdivided into time-frequency zones or segments that exhibit coherent structure. Then the segments tracing back to the same source in auditory STREAMS are grouped.
