Arturia V and FX Collections
Contributed circuit modeling and developed core DSP algorithms of many virtual instruments and effects.
Stefano D'Angelo
Audio DSP engineer & sound researcher
What I do
I design digital audio algorithms for companies, develop tools grounded in scientific research and real-world constraints, and create original products for musicians.
For companies
I help companies research, design, implement, and validate DSP algorithms for software, hardware, and embedded systems.
For technologists and musicians
I create algorithms, tools, and products for developers, researchers, and musicians to explore, test, and shape new directions in sound.
