QCC30xx, Qualcomm aptX, Qualcomm cVc, Qualcomm Active Noise Cancellation, Qualcomm Adaptive Active Noise Cancellation, Qualcomm Truewireless Stereo, Qualcomm TrueWireless Stereo, Qualcomm TrueWireless Mirroring, and Qualcomm QCC5100 are products of Qualcomm Technologies, Inc., and/or its subsidiaries.

Multi-core processing

QCC30xx SoCs offer powerful multi-core processing, designed to enable complex use cases, and helps to support premium audio technologies in these mid-range SoCs.

Support for Qualcomm audio technologies

Variants of the QCC30xx are designed with progressively feature-increasing audio specifications, so that our customers can choose from a wide portfolio of development options. Using a license key mechanism, the highest tier QCC305x SoCs support Qualcomm® aptX™ Adaptive audio, Qualcomm® Adaptive Active Noise Cancellation, Qualcomm® cVc™ Echo Cancellation and Noise Suppression, Qualcomm® aptX™ Voice, and digital assistants with button or wake word activation.

Qualcomm TrueWireless™ Mirroring

Featured on the QCC304x and QCC305x, innovative Qualcomm TrueWireless™ Mirroring technology is designed to deliver a superior user experience by improving robustness and supporting dynamic and seamless bud-to-bud role-swapping with Bluetooth address handover even during run time. True Wireless Mirroring also supports balancing out power distribution between both earbuds.
