Read VI

Owning Palette: Audio Input N Samples VIs

Requires: myRIO Toolkit

Reads values from one or more audio input channels. Use this VI to read multiple samples for each channel at one time.

AudioIn (N Samples) Ref In specifies the reference to the audio input channels from which to read values. Use the Open VI to open a reference to the audio input channels. Do not modify the AudioIn (N Samples) Ref In values.
Number of Samples specifies the number of samples to read. The default is 1,000. Valid values are between 0 and 10,000.
Sample Rate specifies the sampling frequency in hertz of the input signal. The default is 1,000. Valid values are between 1 k and 30 k.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
AudioIn (N Samples) Ref Out returns the reference to the audio input channels from which this VI reads values.
Values returns the values in volts that this VI reads from the audio input channels. The order of the values corresponds to the order in which the Open VI opens the audio input channels.
error out contains error information. This output provides standard error out functionality.
