LabVIEW G API Reference

You can develop test programs with the LabVIEW G APIs provided with Audio and Acoustics Test Software.

The Microphone and Speaker Test RA.lvlib library is located in the C:\Program Files (x86)\National Instruments\LabVIEW version\ProjectTemplates\Source\Audio and Acoustics\Library directory. The library contains APIs in the following categories:

Table 1. LabVIEW G APIs Included in Audio and Acoustics Test Software
Category Description
Acquisition Plays the stimulus signal generated by the Stimulus APIs and acquires the waveform.
Analysis Analyzes the recorded sound waveforms and gets test results.
Calibration Calibrates acoustic-related devices.
Configuration Configures test-related parameters.
Controls Provides common controls used by all APIs.
Limit Configures check limits for frequency/level sweep tests.
Report Provides limit check for each test item and records test result data in report files.
Stimulus Generates stimulus signals and applies mouth equalization curve to the stimulus signals.

Refer to the LabVIEW context help of each API for more information.
