This course introduces the fundamentals of sound synthesis algorithms (everyday, music and speech), digital audio effects and sonification. Multimedia synthetic signals are used in modern digital systems, virtual reality systems, computer animations, games and film. Understanding of theoretical concepts will be consolidated through practical programming assignments in Matlab.

Syllabus of lectures:

1. Introduction to digital audio signal synthesis; musical scale generator

2. Wavetable synthesis; time expansion and compression, time envelopes

3. Concatenative and granular synthesis; parameters, synchronous and asynchronous

4. Additive synthesis and spectral modelling; periodical nonharmonic signals

5. Phase vocoder; signal modification in frequency domain

6. Subtractive synthesis; excitation sources, simple filters, equalizers, color noise

7. Formant synthesis; Klatt synthesizer, cascade and parallel configuration, FOF

8. Linear prediction; cross synthesis speech and music, non-speech sound modelling

9. Modulation synthesis; AM, tremolo, FM, vibrato, alarm, everyday sounds and tools

10. Nonlinear and waveshaping synthesis; Chebyshev polynomials, limiters, distortion

11. Delay effects; echo, reverb, comb and all-pass filters

12. Spatial effects; Doppler effect, panning, hall, Schroeder?s reverb

13. Introduction to physical modelling; digital waveguides, Karplus-Strong algorithm

14. Sonification of biological signals (ECG, EMG, EEG, FCG, EOG), applications

Syllabus of tutorials:

1. Musical scale, Morse code; aliasing, quantization and compression simulation

2. Time and frequency scale modification, clarinet and banjo wavetable synthesis

3. Concatenative speech synthesis, „sci-fi“ sound synthesis

4. Birdcall, brass, bells, gongs, cymbals, banjo, cllarinet and phone synthesis

5. Length changes of audio signals, pitch shift, noise enhancement

6. Synthesis of percussion, plane, wind, waves, violin, steps , consonant „s“

7. Formant synthesis of vowels, music instrument and animal voice

8. Speech, guitar, piano and hammer resynthesis; „cross“ synthesis music and speech

9. Vibrato, tremolo, coins, bubles, alarms, klepání, dřevo, klarinet, žestě, zvony

10. Application of waveshaping to plucked string instruments, percussion and speech

11. Digital reverb implementation (cellar, shover, cathedral)

12. Spatial effects in sérech and music

13. Guitar, harp, piano and drums synthesis

14. Sonification of EEG, ECG, FCG, EMG
