Learning outcomes of the course unit

This course presents a summary of basic knowledge of sound and sound signals as a bearer of music information, its categorization and morphology, particularly with a view to its processing and artificial generation.

Mode of study

Interactive instruction

Prerequisites and co-requisites

Requirements for study are a basic knowledge of high-school physics (particle motion, pressure, time course of physical quantities) and a general awareness of musical instruments.

Course contents

  1. This course, Music Acoustics and its relationship to sound design; Music sound; osscilation, hearing perception, sound and music signal (natural and artificial) definition
  2. Subjective perception: Requirements for the subjective existence of sound signals, sound perception threasholds
  3. Properties of a sound signal: objective, subjective (mustual relationships and dependencies)
  4. Time and frequency domains of a signal: Sound signal analysis methods in the time domain (periodicity, correlation); Methods of sound analog frequency analysis (band filters and their properties)
  5. Signal digital frequency analysis methods, DFT, FFT, anti-aliasing, weighting, average spectrum, cepstrum, wavelette
  6. Music signal transfer, types of transfer, its axis and links; Static and dynamic signal concept, definition of tone and noise
  7. Transient and semi-wave, bounce status, dynamic fluctuation, tremolo
  8. Three-dimensional depiction of a music signal: Dynamic level (time package, percussive, non-percussive, tremolo), melodic (frequency, immediate frequency, harmonicity, vibrato), harmonic (basic classification of music signals).
  9. Signal classification: periodic signals and their frequency spectrum, modulated and quasi-periodic signals, coincidental, transient and continual signals
  10. Time dependent spectra and their objective and subjective interpretations; Synthesis of sound signals: definition and philosophy
  11. Psycho-acoustics: Interaction of man - sound, psycho-acoustic experiments, basic psycho-acoustic dimensions of sound color
  12. Psycho-acoustic events: masking, reverb, combination tones, critical spread bands.
