Smart Audio Platform

The Qualcomm Smart Audio Platform is designed specifically to help streamline the process for developing smart and networked speakers at a range of price points, based on APQ8009.

Qualcomm Smart Audio Platform, Qualcomm aptX, Qualcomm DDFA, and APQ8009 are products of Qualcomm Technologies, Inc. and/or its subsidiaries.

Integrated, single-vendor platform

Helps to more efficiently scope and design a smart speaker, reduce BOM sources, eliminate the need to develop, integrate and tune complex far-field voice technologies with wake-word detection and beamforming, as well as helping reduce Wi-Fi certification time and cost.

Superior far-field voice, noise suppression and keyword detection

Supports superior voice performance and reduce voice UI development complexity with our multi-microphone far-field voice and wake-word detection, noise suppression, beamforming and stereo echo cancellation technology, pre-tuned and available with a comprehensive example design.

Supports multiple premium audio features

Designed to support world-class connectivity and Bluetooth/Wi-Fi coexistence, high definition (24-bit) audio and networked audio, our proprietary technologies including Qualcomm® aptX™ audio and compatibility with our Qualcomm® DDFA™ digital amplifier and leading voice services.

Comprehensive development kit

Further reduce development time and complexity for richly featured smart speakers using our unique development kit with end-to-end example design. As well as its other components, the kit includes a Wi-Fi certified system-on-module, reference speaker casing with bi-amped, two-way speakers, and a six-microphone array board for high performance far-field voice user interface.
