Writes data from a waveform or an array of waveforms to a .wav file.

Programming Patterns

To create a sound file reference, use the Sound File Open node and wire the absolute path of a .wav file to the sound file input. Then, wire the reference output of Sound File Open to the input of this node.

connector_pane_image
datatype_icon

reference in

Reference to the .wav file in memory.

datatype_icon

data

Sound data to write 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.

This input accepts the following numeric data types:
  • An array of waveforms, where the Y array contains single-precision, floating-point numeric data
  • An array of waveforms, where the Y array contains double-precision, floating-point numeric data
  • A single waveform of double-precision, floating-point numeric data
  • An array of waveforms, where the Y array contains signed 16-bit integer data
  • An array of waveforms, where the Y array contains signed 32-bit integer data
  • An array of waveforms, where the Y array contains unsigned 8-bit integer data

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

reference out

Reference to the .wav file specified by reference in.

error out

Error information.

The node produces this output according to standard error behavior.
