The is an essential utility for developers and engineers working with the Qualcomm® AudioReach™ Signal Processing Framework (SPF). It provides a graphical environment to design, tune, and calibrate audio and voice algorithms for devices powered by Snapdragon® mobile platforms. Key Features of QACT
: Developers download QACT through the Qualcomm Package Manager , which ensures all necessary plugins and licenses are properly installed.
: 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. qualcomm audio calibration tool
: 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.
: It integrates with the AudioReach SPF , allowing for run-time graph modification and real-time resource monitoring. The is an essential utility for developers and
: 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
: It provides detailed insights into DSP utilization, including per-module and per-thread CPU load. : Once connected, users can access specific modules
: 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
