Psychoacoustic Foundations & Signal Processing

This lecture covers the psychoacoustic foundations of sound perception, including how sound travels through air, reaches the ear, and is processed by the brain. It also delves into signal processing topics such as wave files, spectrograms, Fourier Transform, and matrix factorization. The instructor explains the concepts of longitudinal waves, the anatomy of the ear, cochlear response to different frequencies, and the brain's interpretation of sound frequencies. Additionally, the importance of sample rate in wave files and the analysis of spectrograms for tasks like automatic music transcription are discussed.
