Use MATLAB to acquire and analyze data from Windows sound cards.
MATLAB® supports sound cards through Data Acquisition Toolbox™ using both legacy and session-based interfaces. Specifically, it supports 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.
Using the session-based interface provided by the toolbox, you can perform the following tasks on both 32-bit and 64-bit MATLAB:
The Data Acquisition Toolbox legacy interface, which is available only on 32-bit MATLAB, supports up to two audio channels. The toolbox provides Simulink® blocks that enable you to acquire and send live sound data to and from Simulink models. For more advanced Simulink sound card support, see Audio Support from DSP System Toolbox™.
Session-based interface available on 32-bit and 64-bit Microsoft Windows only.
Legacy interface available on 32-bit Windows only.
