Subject guarantor:

Zdeněk OTČENÁŠEK

Name of lecturer(s):

Zdeněk OTČENÁŠEK

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.
