Xavier Serra was born in Barcelona (Catalonia, Spain) and from a very young age he maintained a dual interest in music and science. He started musical studies when he was 11 years old, studying classical guitar and cello at the Conservatory of Barcelona (graduated in guitar in 1981) and then he combined those studies with the studies of Biology at the University of Barcelona (BSc in Biology in 1981).
After completing his undergraduate education and with a scholarship from a Catalan bank, he continued his studies in the USA. He did a Master in Music at Florida State University (graduated with honours in 1983), where he was able to combine music performance with a formal education in computer music in one of the few centres that at that time offered this possibility. In 1983 he obtained a Fulbright scholarship to do a PhD and was accepted at Stanford University to work at the Center for Computer Research in Music and Acoustics (CCRMA), specializing in audio signal processing for music applications. At CCRMA, he studied with pioneers in the field like John Chowning, Max Mathews and Julius Smith. Xavier Serra obtained his PhD in 1989 with a thesis entitled: A System for Sound Analysis/Transformation/Synthesis based on a Deterministic plus Stochastic Decomposition.
