The NI myRIO-1900 model provides audio input and output channels. You can use the audio channels to perform audio acquisition and playback.

Use the following methods to access the audio input and output channels.

Method Audio Input Audio Output
myRIO Express VIs Use the Analog Input Express VI and select the AudioIn/Left or AudioIn/Right channel in the Configure Analog Input dialog box. Use the Analog Output Express VI and select the AudioOut/Left or AudioOut/Right channel in the Configure Analog Output dialog box.
myRIO Advanced I/O VIs Use the Open VI on the Analog Input palette to open a reference to the audio input channels. Use the Open VI on the Analog Output palette to open a reference to the audio output channels.
FPGA Interface Nodes Use the Open FPGA VI Reference function to open a reference to the NI myRIO shipping personality and wire the output reference to the Read/Write Control function to access the audio input channels. Use the Open FPGA VI Reference function to open a reference to the NI myRIO shipping personality and wire the output reference to the Read/Write Control function to access the audio output channels.

Refer to the Clap Sensor sample project and Voice Recorder sample project for examples of using the audio channels on the NI myRIO. In LabVIEW, select File»Create Project to display the Create Project dialog box. You can find these two sample projects under Sample Projects»myRIO.
