Reads 32-bit signed integer numeric data from a sound input device.
The Y component of the waveform this node returns is an array of signed 32-bit integers.
To create a task ID, use the Sound Input Configure node and wire the task ID output to the input of this node.
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.
Default: 10,000
Reference to the configured sound device you want to manipulate or input.
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.
Default: No error
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
Reference to the configured sound device originally passed to the task ID in parameter.
Any sound data read from the file. For multi-channel sound data, data is an array of waveforms where each element of the array is a single channel.
