    2. Table of Contents INTRODUCTION PROJECT OVERVIEW THE PREPROCESSOR THE LEARNING PROCESSOR THE SEPARATION PROCESSOR PROJECT EXPERIMENTS CONCLUSION

    3. INTRODUCTION Overview of sound source separation Sound separation methods Related applications of sound separation

    4. Overview of sound source separation What is sound separation? Psychoacoustic properties Timbre How can sound be modeled?

    5. Sound separation methods CASA (Computational Auditory scene Analysis), Marrian Spatial and Periodicity-and-Harmonicity CASA: 3D Correlogram analysis Blind source separation and prediction-driven

    6. Related applications of sound separation Sound and voice recognition Noise removal Compression

    7. PROJECT OVERVIEW Overview Auditory model analysis Sound data library and classification Sound data matching Complete sound separation system

    8. Overview What is a piano sound? Memory Clustering

    9. Auditory model analysis Properties Grouping Past knowledge Correlation

    10. Sound data library and classification Sound memory How much information is needed for later analysis? Does it matter if audio data is compressed? Structure of classification

    11. Sound data matching

    12. Complete sound separation system

    13. THE PREPROCESSOR The Cochlea Filter Model Correlogram 3-D Correlogram

    14. The Cochlea Filter Model Filtering: basilar membrane (BM) Detection: inner hair cell (IHC) Compression: automatic gain control (AGC) Cochleagram

    15. Lyon cochlear model

    16. Correlogram Short time auto-correlations of the neural firing rates as a function of cochlear place (best frequency) versus time Correlogram movie

    17. Correlogram Speech processing Extract the formants of voiced and unvoiced sounds Short duration Auto-correlation window size
