Audio

Oftentimes just acquiring analog and digital signals isn’t sufficient; highly controlled manipulations are required e.g. for hearing aids, noise cancelling headphones, or car acoustics.

Speedgoat real-time systems providing high performance, high-resolution analog and digital I/O, together with MATLAB & Simulink from MathWorks, are a powerful environment for analog and digital signal processing, and for desktop and real-time simulation.

Common Applications

Hearing aid devices and cochlear implants
Noise cancelling headphones
Active noise controls to improve car and plant acoustics

Real-time Audio Acquisition and Processing

Capabilities

Hardware

Low latency, high resolution 16, 18, and 24-bit analog I/O modules
High performance Real-time target machine supporting closed-loop rates of up to 20 kHz for execution on CPUs, and above 20 kHz for execution on FPGA-based I/O modules
XLR and BNC panels to connect with microphones and speakers etc.
Your project specific sample rate, I/O, and environmental requirements guaranteed to be met

Software

Design your signal processing model in MATLAB & Simulink, drag and drop Speedgoat I/O driver blocks, and configure signal parameters via easy to use dialog fields
Autogenerate C/HDL code from Simulink controls design and execute on multi-core CPUs and optional FPGAs
Simulate and test your real-time application running on a Speedgoat real-time target machine using Simulink Real-Time
Deploy your applications for stand-alone execution on a Speedgoat real-time target machine, or use Embedded Coder to implement code on your own video acquisition and controls devices

Benefits

Save costs and reduce risks

Rapidly design, implement and test complex signal processing algorithms on a real-time system, without having to build expensive hardware that's difficult to debug
No need to develop complete hardware systems for mass deployment in the early stages of development: Real-time systems can be expanded with additional I/O at any time, and multi-core CPUs and FPGAs scale well in case sample rate and frequency requirements change
Automate and perform extensive tests with your physical hardware at a very early stage, and reduce the likelihood of costly design flaws

Shorten time-to-market

Shift the traditional sequential V-diagram to a circular workflow to enable continuous verification and validation of your designs at the earliest possible stages
Seamless Model-Based Design workflow support along the entire development cycle including modeling, prototyping, testing, documentation, and embedded integration
