It includes "diff/merge" capabilities to help teams manage and combine different tuning versions. Integration with AudioReach™
Devices must pass rigorous certification tests, such as Microsoft Teams certification, Amazon Alexa Voice Service (AVS) requirements, or carrier-specific cellular voice standards. QACT provides the precise granularity required to tweak acoustic parameters to hit these strict target curves. The QACT Workflow: Step-by-Step
To simplify the user experience and ensure license compliance, Qualcomm has integrated QACT into the Qualcomm Package Manager. During installation, the manager confirms your developer licenses and installs necessary add-ons or plugins required for specific Snapdragon platforms. qualcomm audio calibration tool
Prevents audio clipping and distortion at high volumes while boosting quiet sounds.
What (e.g., Snapdragon mobile, QCC Bluetooth SoC) are you targeting? It includes "diff/merge" capabilities to help teams manage
Before launching QACT, ensure that the target device (e.g., an Android smartphone or development board) is properly connected via USB. must be installed and running. QACT utilizes QPST’s virtual COM port to communicate with the device's DSP. Engineers must verify that the device’s USB drivers are installed and that the COM port is visible in the Windows Device Manager.
Voice communication requires stripping out the speaker’s output from the microphone's input. QACT provides detailed visual representations of echo paths, allowing engineers to fine-tune linear and non-linear echo suppressors for crystal-clear speakerphone performance.

When you switch from a phone call to a video call (Zoom/Skype), the audio path changes. The modem no longer handles the audio; the application processor does. ACT allows engineers to define different calibration profiles for different "Use Cases":
For fine-tuning, engineers connect a physical development board (like an RB3 Gen 2 or a smartphone) via QPST. Inside QACT, they click "Connect To Device". The software then connects to the DSP. The engineer plays a test tone or music, and adjusts the DRC or EQ sliders. On newer AudioReach versions, the audio changes instantly, allowing the engineer to listen to the result in real-time.
