In this project two digital audio effect plugins (VSTs) are proposed to simu- late an automatic infinity sustain and reverb respectively. Sustain audio ef- fect algorithm is based on convolution with velvet noise. For reverberation, a Modulated Velvet Feedback Delay Network implementation will be used. The use of velvet noise enhances rever- beration with a quick built of early re- flections in comparison with standard Feedback Delay Networks. The Mod- ulation approach produces interest- ing deep/psychedelic sounds which model unreal spaces. Both VSTs are thought to work together allowing the user to place them in her/his favourite configuration (e.g. Sustain in series with reverberation). A technical evalu- ation (impulse response, White Gaus- sian Noise response and T60 times) is performed regarding the different pos- sible combinations of plugins. Also, a Two Alternative Forced Choice test and a survey about the VST perfor- mance are carried out for a more subjective sound and plugin evalua- tion. Results are that The Velvet Cloud plugins are unique, achieve a deep, psychedelic reverberation with micro- variations thanks to modulation with a background infinity sustain over musi- cians can play melodies on top.
