Synopsis:

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
