Digital Audio Effects, talk 3: Modulators and Demodulators

Presenter: Gilmar Rocha de Oliveira Dias

In these DAFx talks, the main concepts in the field of audio effects processing will be presented. In the third talk of the series, basic modulation techniques will be presented by introducing simple schemes for amplitude modulation, single-side-band modulation and phase modulation with its use in audio effects. Following, will be seen the demodulators, which extract parameters of the incoming signal for further effects processing. The combination of these techniques lead to more advanced audio effects, which will be demonstrated by several examples.
