: When a device is connected, QACT can perform online calibration , allowing engineers to hear the results of parameter changes—such as EQ, bass boosting, or noise cancellation—as they make them.
This guide provides an in-depth look at what QACT is, how it works, and why it is indispensable for audio engineers. What is the Qualcomm Audio Calibration Tool (QACT)?
In QACT, navigate to File > Save to save your working workspace.
In the high-stakes world of embedded audio, the difference between a "tinny speaker" and a "premium sound experience" is often a matter of precise tuning. This is where the , also known in its modern iteration as AudioReach Creator (ARC) , becomes an indispensable asset for audio engineers and embedded systems developers.
Every adjustment made in QACT is saved into ACDB files (typically with .acdb extensions). These files contain specific parameters for different use cases. Examples include handset voice calls, speakerphone playback, and Bluetooth SCO routing. Essential Calibration Modules
: A modular framework running on the Hexagon™ DSP that executes the actual audio processing modules.
