Sound File Info (G Dataflow)

Last Modified: March 15, 2017

Retrieves data about a .wav file.

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

reference in

Reference to the sound file.

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

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 out

Reference to the sound file specified by reference in.

datatype_icon

total number of samples/ch

Total number of samples per channel in the .wav file.

datatype_icon

sound format

Sample rate, the number of channels, and the number of bits per sample in the .wav file.

datatype_icon

sample rate (S/s)

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

datatype_icon

number of channels

Number of channels in the .wav file.

This output 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.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
