My name is Sean Costello. I have been developing audio DSP for the past 15 years, with 14 of those years in a professional context. My early work was in an academic context, using Csound as my programming environment.
I joined a small startup company in 1999 (Staccato Systems) that was developing physical models for video games, and spent way too much time working on car engine sounds. In 2001, Staccato Systems was purchased by Analog Devices, where I spent the next 6 years working on audio algorithms and development tools for the SHARC and Blackfin DSPs.
From 2007 through 2009, I have been working as a consultant, creating a wide variety of (mostly) interesting audio algorithms for a variety of clients. Since 2010, I have released a number of audio plugins (VST/AU/RTAS/AAX) through my own company, Valhalla DSP.
My goal with this blog is to talk about some of the audio DSP subjects that I am obsessed with, in a manner that bridges the technical with the musical and philosophical.
