Check the System Requirements
To install a hardware support package, you must have a supported product release, along with the required operating system and base product.
View the hardware support package system requirements table and confirm you have:
- A supported release
- A supported operating system
- The required base products
If you do not have a supported release or the required base products, you can get started with a free trial, or you can purchase products.
Continue with the Installation
After confirming you have the system requirements, proceed with either installation option listed below.
Option 1: Using the Toolstrip
Launch the Support Package Installer from your version of MATLAB and navigate to the correct support package.
Option 2: "Get Support Package" Button (.mlpkginstall file*)
Clicking the Get Support Package button provides the support package install file:
([filename].mlpkginstall)
There are several ways to initiate the Support Package Installer from these files:
- Open the
.mlpkginstallfile directly from your Internet browser. - Download and save the file (the default option for some Internet browsers), and open it directly from your Windows, Mac, or Linux operating system.
- Open the
.mlpkginstallfile directly from within MATLAB by navigating the Current Folder to the location of the downloaded file and double clicking it. That will initiate the installation for the MATLAB release that you have open.
The primary difference between using the .mlpkginstall file (option 2) rather than the toolstrip (option 1) to initiate support package installation is that the file allows the user to avoid the support package selection screen on the installer.
*These file types were introduced in MATLAB R2013a.
Users without an Internet connection can install hardware support packages by following the download instructions.
MATLAB and Data Acquisition Toolbox support Windows® compatible sound cards that use the DirectSound driver. Use MATLAB as your single software environment to create your own waveforms, measurement and analysis routines, and to develop automated applications that use sound card data.
Use MATLAB to perform the following tasks on Windows sound cards:
- Acquire data from multiple audio input channels
- Generate audio data for multiple audio output channels
- Configure the sound card sampling rate and other settings
- Analyze sound card data as it is being acquired
- Trigger the start of your data acquisition
- Easily switch sound cards with minimal changes to MATLAB code
Platform Support
Available on 64-bit Windows only.
