Sound Input Read (I16) (G Dataflow)

Last Modified: March 15, 2017

Reads data from a sound input device. You must use Sound Input Configure to configure the device.

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

The Y component of the waveform this node returns is an array of signed 16-bit integers.

datatype_icon

number of samples/ch

Number of samples per channel in the buffer. Use a large number of samples for continuous operations. Use a smaller number of samples if you want to use less memory.

datatype_icon

task ID in

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

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

timeout

Time, in seconds, that the node 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.

Default: 10

datatype_icon

task ID out

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

datatype_icon

data

Any sound data from the file. For multi-channel sound data, data is an array of waveforms where each element of the array is a single channel.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
