Sound Output Configure (G Dataflow)

Last Modified: January 12, 2018

Configures a sound output device to receive data. Use Sound Output Write to write data to the device.

datatype_icon

number of samples/ch

Number of samples per channel in the buffer. Continuous operations require an increased number of samples to improve data quality but require the use of more memory.

Default: 100,000

datatype_icon

sample mode

Setting to generate samples once or continuously.

Name Value Description
Finite Samples 0

Generate samples once. This mode calls Sound Output Write and only writes until you reach the number of samples specified in number of samples/ch.

Continuous Samples 1

Generate samples continuously. This mode calls Sound Output Write repeatedly as needed.

Default: 1—Continuous Samples

datatype_icon

device ID

The input or output device you access for a sound operation. The value ranges from 0 to n-1, where n is the number of input or output devices on the computer.

Default: 0

datatype_icon

sound format

The acquisition rate, the number of channels, and the bits per sample of the sound operation. The values for each of these elements is dependent on your sound card.

Not all operating systems and sound cards support all sample rate (S/s), number of channels, or bits per sample options.

Performance Details

sample rate (S/s) and bits per sample use more computer memory when set to a higher value.

datatype_icon

sample rate (S/s)

Sampling rate for the sound operation. Common rates are 44,100 S/s, 22,050 S/s, and 11,025 S/s.

Default: 22,050 S/s

datatype_icon

number of channels

Number of channels. This input can accept as many channels as the sound card supports. For most sound cards 1 is mono and 2 is stereo.

Default: 2

datatype_icon

bits per sample

Quality of each sample in bits. Available resolutions are 8 bits, 16 bits, and 32 bits.

Default: 16 bits

datatype_icon

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

task ID

Reference to the configured sound device. You can pass task ID to other sound operation nodes.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
