MATLAB is the tool of choice for most engineers when they are in the early stages of signal processing algorithm development. This is true in the audio industry as in many others. Today, we will illustrate a workflow for developing and testing audio algorithms in MATLAB, using the newly released Audio System Toolbox. This new toolbox accelerates the development and testing of audio processing algorithms by allowing engineers to run and interactively tune their MATLAB code live on their desktops. The key capabilities include low-latency real-time streaming connectivity to audio devices, automatic generation of VST plugins to run custom MATLAB code natively on digital audio workstations, and a reference library of algorithms, analysis, and visualization aids.

Darel Linebarger joined MathWorks in May of 2000, where he now manages their Signal Processing and Communications System Design group. Prior to that, he was on the electrical engineering faculty of the University of Texas at Dallas for twelve years. He has authored or co-authored numerous papers and patents and is a Senior Member of the IEEE. He holds an M.S. and Ph.D. from Rice University.





Charlie DeVane is the senior developer of the Audio System Toolbox for MATLAB, chiefly responsible for audio plugin and MIDI features. He also teaches Computer Science in the Sound Recording Technology program at UMass Lowell. Charlie is an active member of the Boston Section of the AES, plays out occasionally on fretless bass, and is pretty sure his project studio will never be completed. He is a senior member of the ACM, and holds an MEng in Computer Science from Cornell University, a BSEE from NC State, and 11 patents.



MathWorks is located off Route 9 East in Natick. When you arrive, follow the signs to visitor parking, which is located in front of the Apple Hill One building. Our reception area is located just inside the main entrance of Apple Hill One. For detailed directions see
