Working with Audio
In this example, you u se the From Multimedia File block to import a video
stream into a S imulink mode l. You also use Signal Process in g Blockset From
Wave File block to import an audio stream into the model. Then you write
this audio and video to a single file using the To Multimedia File block.
This procedure assumes you are working on a Windows platform:
1 Create a new Simulink model, and add to it the blocks shown in the
following table.
