Seminar contents and practical implementation

The aim of this seminar is to study the main fields of digital audio effects, based on the above-mentioned book.

There are many audio signal processing methods that are widely used in audio production and commercial products. Such methods include, for example, audio-specific filters (time-varying filters, comb filters, etc.), sound spatialisation and reverberation, time stretching and pitch shifting, phase vocoder effects, sinusoidal modeling, nonlinear effects etc.

The first lecture is given by the instructor. The rest of the seminar consists of student presentations. Topics are assigned on the first lecture. In practice:
