Sound Output Write (G Dataflow)

Last Modified: March 15, 2017

Writes data to a sound output device. You must use Sound Output Configure to configure the device if you are writing continuously.

You must have DirectX 8.0 or later to use this VI.

Note  

If the buffer you set using the number of samples/ch input of Sound File Read is full when the application executes, an automatic wait is implemented on Sound Output Write even if you set timeout to 0. This may cause the data flow to hang and return unexpected results.

task ID in

The sound operation from the configured device you want to manipulate or input. Use Sound Output Configure to generate a task ID.

datatype_icon

data

Sound data written to the .wav file. For multi-channel sound data, data is an array of waveforms where each element of the array is a single channel.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

timeout

Time, in seconds, that the function waits for the sound operation to complete. This node returns an error if the time elapses. If you set timeout to -1, the node waits indefinitely. If you set timeout to 0, the node returns immediately while the sound continues to play. You can use Sound Output Wait to wait for playback to complete.

Default: 10

datatype_icon

task ID out

The manipulated sound operation originally passed to the task ID parameter.

error out

Error information.

The node produces this output according to standard error behavior.
