REQUIRED TEXTBOOK : Signals Sound and Sensation by William M. Hartmann.
REFERENCE TEXTBOOKS: (not required purchases) Excerpts from the following texts may be provided, as well as current research papers in the field of Music Information Retrieval
Bregman, Albert S., Auditory Scene Analysis: The Perceptual Organization of sound .

Yost, William A., Fundamentals of Hearing: An Introduction
COURSE COORDINATOR: Prof. Bryan Pardo
COURSE GOALS: How do you tell the sound of a clarinet from the sound of a kazoo? Is this song a waltz or a tango? If your friend likes Yo La Tengo, would she prefer a CD by the Flaming Lips or Bon Jovi? Can a computer answer these questions?
Researchers in computational music perception apply signal processing, psychology, music theory, machine learning, and natural language processing techniques to auditory user interfaces for human-computer interaction. Current application areas include vocal interfaces and search engines for music databases, machine accompaniment of human musicians, automated music recommendation systems, and tools for music production.
Machine Perception of Music will introduce students to the field of computational music perception through a combination of lectures, readings, and lab work in MATLAB. Students will learn basics of how sound and music are recorded and encoded by computers as .wav and MIDI files. The class will also explore basics of audio perception, including the relationship between pitch and frequency and the difficulties inherent in auditory scene analysis by humans and machines. Basic classification and sequence alignment techniques will also be introduced.
Prior programming experience sufficient to be able to do laboratory assignments in MATLAB is required. Completion of the Engineering Analysis ( GEN_ENG 205-2 ) series or EECS 211 or EECS 231 would demonstrate sufficient experience.
An ability and willingness to
1) … learn about things outside your own area of expertise.
2) ….come up with something cool and MAKE it in software.
3) ….think scientifically about the arts. (Yes, it IS possible)
DETAILED COURSE TOPICS: What follows is an example syllabus. As topics of current interest in machine perception of music shift, course content will vary to reflect research trends.
Week 1: Pure tones, power, intensity and loudness
Week 2: Perception of periodic complex sounds, auditory filters, critical bands
Week 3: Musical measures of frequency, pitch perception, MP3 encoding
Week 4: Representations of audio: spectrograms, cepstrograms
Week 5: Music theory (chords, scales, time signatures) and MIDI
Week 6: Beat tracking, finding rhythms
Week 7: Pitch tracking, melody transcription
Week 8: Source separation and scene analysis
Week 9: Audio fingerprinting, query by humming, melody matching
Week 10: Music recommendation systems, current research in MIR
Three written assignments (30%)
Three laboratory projects (30%)
Final project (20%)
