Document Summary

The challenge is that all of these sounds are coming into our ears as a single complex waveform. Every sound has individual complex wave sound and all sounds come together to make one single complex waveform that goes into our ears. We need to separate out all of these things. As the auditory stream, waveform is coming into our ears how do we continue to track the individual sources as the sounds unfold over time. Typically, as sounds unfold in the world change over time. The challenge is keeping track of a single sound as it changes over time. We need to analyze the different sources of sounds from the environment. Auditory scene analysis requires properly grouping different components of sound. Auditory scene analysis is the process by which we extract information. Simultaneous grouping: allows us to group sounds together. Analyzing the sound source in time (do sounds come from the same source over time as they change)
