Sound File Open (Sound File Write Open) (G Dataflow)

Last Modified: March 15, 2017

Opens a .wav file for writing.

connector_pane_image
datatype_icon

sound file

Absolute path to the .wav file.

If the path is empty or invalid, the node returns an error.

This input appears when you wire a file path to sound file. If you wire a reference to sound file, this input changes to reference in

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 controls is dependent on your sound card.

Not all operating systems and sound cards support all sound format options.

Performance Details

sample rate (S/s) bits per sample
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. The default is 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.

datatype_icon

bits per sample

Quality of each sample in bits. Common resolutions are 16 bits and 8 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

reference

A reference to the sound file. You can pass reference to other Sound Files nodes.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
