Sound File Info (G Dataflow)

Absolute path to the .wav file.

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

If you wire a reference to sound file, this input changes to reference in.

Reference to the .wav file in memory.

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

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 to the .wav file specified by reference in.

This output is available only when you wire a reference to sound file.

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

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

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.

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.

bits per sample

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

The node produces this output according to standard error behavior.

This node can return the following error codes.
