New Features and Changes
Learn about updates—including new features and behavior changes—introduced in each version of the Digital Audio Acquisition and Generation Toolkit.
Digital Audio Acquisition and Generation Toolkit 2023 Q3 New Features and Changes
- Introduces PCM acquisition and generation APIs which you can configure to acquire and generate PCM signals of different serial audio interface types. I2S acquisition and generation APIs are obsolete as of Digital Audio Acquisition and Generation Toolkit 2023 Q3.
- Allows the same hardware device to synchronously acquire and generate PCM signals of the same or different serial audio interface types.
- Increases the maximum number of timing engines to 4 when synchronously acquiring and generating or only acquiring PCM signals with the PXIe-7820/7821. The maximum number of timing engines for PCM generation is 2 whenever synchronously acquiring and generating or only generating PCM signals.
- Changes the toolkit name from LabVIEW PDM Acquisition Toolkit to Digital Audio Acquisition and Generation Toolkit.
- Adds support for LabVIEW 2022 and removes support for LabVIEW 2018 SP1 Patch.
Digital Audio Acquisition and Generation Toolkit 2022 Q4 New Features and Changes
- Adds support for 64-bit LabVIEW 2018 SP1 Patch, 2019, 2020, and 2021.
- Provides C# APIs and examples.
Digital Audio Acquisition and Generation Toolkit 2021 Q4 New Features and Changes
- Adds support for acquiring, converting, and generating I2S signals.
Digital Audio Acquisition and Generation Toolkit 2021 Q2 New Features and Changes
- Adds support for generating PDM signals.
- Adds support for different rates and decimation factors.
- Adds support for PXIe-7821 and USB-7845/7846.
