Audio System Toolbox

Design and test audio processing systems

Audio System Toolbox™ provides algorithms and tools for the design, simulation, and desktop prototyping of audio processing systems. It enables low-latency signal streaming from and to audio interfaces, interactive parameter tuning, and automatic generation of audio plugins for digital audio workstations.

Audio System Toolbox includes libraries of audio processing algorithms (such as filtering, equalization, dynamic range control, and reverberation), sources (such as audio oscillators and wavetable synthesizers), and measurements (such as A- and C-weighting). Interfaces to external MIDI controls and low-latency audio drivers such as ASIO™, ALSA, and CoreAudio enable you to validate multichannel audio designs in MATLAB® or Simulink®. You can generate VST plugins from MATLAB code. For simulation acceleration or desktop prototyping, the toolbox supports C/C++ code generation.

Algorithms are available as MATLAB functions, System objects, and Simulink blocks.

Key Features

  • VST plugin generation for digital audio workstations

  • Interfaces to ASIO, ALSA, CoreAudio, and other low-latency audio drivers

  • Interfaces to MIDI controls for real-time tuning of MATLAB and Simulink simulations

  • Audio processing algorithms, sources, and measurements for crossover and equalization filtering, dynamic range control, reverberation, wavetable synthesis, and other tasks

  • Support for C code generation

WLAN System Toolbox

Simulate, analyze, and test the physical layer of WLAN communications systems

WLAN System Toolbox™ provides standard-compliant functions for the design, simulation, analysis, and testing of wireless LAN communications systems. The system toolbox provides configurable physical layer waveforms for IEEE® 802.11ac™ and 802.11b/a/g/n/j/p standards. It also provides transmitter, channel modeling, and receiver operations, including channel coding, modulation (OFDM, DSSS, and CCK), spatial stream mapping, channel models (TGac and TGn), and MIMO receivers.

You can generate very high throughput (VHT), high throughput (HT-mixed), and legacy (non-HT) signals, and demodulate VHT, HT-mixed, and non-HT OFDM signals. You can also perform measurements such as channel power, spectrum mask, and occupied bandwidth, and create test benches for the end-to-end simulation of WLAN communications links.

The system toolbox provides reference designs to help you explore baseband specifications and study the effects of RF designs and interference sources on system performance. Using WLAN System Toolbox with hardware support packages, you can connect your transmitter and receiver models to radio devices and verify your designs via over-the-air transmission and reception.
