: QACT is the primary tool used to edit the Audio Calibration Database (ACDB) , which stores tuning parameters for various audio modules and use cases on the device. The Calibration Process

: Designers can create new audio signal flow graphs or modify existing ones using a GUI-based Integrated Development Environment (IDE). qualcomm audio calibration tool

: It provides detailed insights into DSP utilization, including per-module and per-thread CPU load. : QACT is the primary tool used to

Using QACT involves several distinct phases, from initial connection to final deployment: Using QACT involves several distinct phases, from initial

: After refining the parameters, changes are saved to an .acdb file. This file is then placed in the /etc/acdbdata/ folder on the device file system, where the ACDB Management Layer (AML) loads them during system initialization. Why QACT Matters

: Once connected, users can access specific modules like the Equalizer , Echo Cancellation (ECNS) , or Noise Suppression . For example, a speaker equalizer can be adjusted by dragging stage points in the GUI to change gain and frequency values in real-time.

: To perform "Online Tuning," the PC running QACT must connect to the target hardware. This is typically done by selecting the appropriate processor (e.g., Proc 0) within the tool's interface.
