My name is Sean Costello. I have been developing audio DSP for the past 11 years, with 10 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.
Since 2007, I have been working as a consultant, creating a wide variety of (mostly) interesting audio algorithms for a variety of clients. I am currently working on a number of VST, AU, and RTAS plugins, as well as my own set of low-level C++ audio modules that should be portable to a variety of platforms. The first plugin, ValhallaFreqEcho, was released in March 2010, and can be downloaded from http://www.valhalladsp.com.
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.
