Configures a sound input device to acquire data and then sends the data to a buffer. Use Sound Input Read to read the data.
Number of samples per channel in the buffer. Continuous operations require an increased number of samples to improve data quality but require the use of more memory.
Default: 100,000
Setting to acquire samples once or continuously.
Name | Value | Description |
---|---|---|
Finite Samples | 0 | Acquire samples once. In this mode, call this node only until you have written the number of samples specified in number of samples/ch. |
Continuous Samples | 1 | Acquire samples continuously. In this mode, you can call this node repeatedly as needed. |
Default: 1—Continuous Samples
The input or output device you access for a sound operation. The value ranges from 0 to n-1, where n is the number of input or output devices on the computer.
Default: 0
The acquisition rate, the number of channels, and the bits per sample of the sound operation. The values for each of these elements is dependent on your sound card.
Not all operating systems and sound cards support all sample rate (S/s), number of channels, or bits per sample options.
Performance Details
sample rate (S/s) and bits per sample use more computer memory when set to a higher value.
Sampling rate for the sound operation. Common rates are 44,100 S/s, 22,050 S/s, and 11,025 S/s.
Default: 22,050 S/s
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.
Default: 2
Quality of each sample in bits. Available resolutions are 8 bits, 16 bits, and 32 bits.
Default: 16 bits
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
Reference to the configured sound device. You can pass task ID to other sound operation nodes.
Error information.
