Abstract

This workshop is composed of 2 sections: Audio processing and Wireless Communications. The first section will present the new Audio System Toolbox. This toolbox helps you stream live audio in and out of MATLAB/Simulink along with algorithms and tools for processing, tuning, and analyzing such live audio signals. The toolbox also enables low-latency processing via ASIO support on Windows or Core Audio support on Mac desktops. Through demonstrations, you will learn how easy it is in MATLAB to:
  • Tune parameters that affect the live audio stream (such as the bandwidth of a filter) by using a graphical interface and/or a MIDI device
  • Generate VST audio plugins from MATLAB code and to manage inter-process communication between digital audio workstations (DAWs) and MATLAB for real-time analysis of audio signals while engaging in high-performance audio processing in the DAW
  • Host existing VST plugins in MATLAB to run/tune your favorite VST plugin directly from inside MATLAB with both a programmatic and a graphical interface.
  • Deploy audio algorithms from Simulink to mobile devices such as iPads and Android tablets.
In the 2nd section, we showcase how to test your wireless design prototypes on radios and verify system performance by connecting your MATLAB algorithms to SDR devices. We will use MATLAB and Simulink to compose algorithms and test-benches and perform over-the-air experiments with Software-Defined Radios (SDR) such as USRP or ADI Pluto Radio.
