Qualcomm Audio Calibration Tool [new] May 2026

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

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

For manufacturers of everything from wearables to automotive systems, QACT reduces the cost and time of development by allowing "off-target" design that easily migrates to "on-target" hardware. It supports high-fidelity audio standards and advanced features like Qualcomm Aqstic™ and cVc™ noise cancellation , ensuring premium sound quality across diverse environments.

: 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

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 : Designers can create new audio signal flow

: It integrates with the AudioReach SPF , allowing for run-time graph modification and real-time resource monitoring.

: It provides detailed insights into DSP utilization, including per-module and per-thread CPU load. Qualcomm® Audio Calibration Tool | Qualcomm Developer :

: 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.

: Engineers can modify audio parameters and see (or hear) the results instantly while the use case is running.
