Integrated LE Audio and Classic Bluetooth audio

QCC3071 is qualified for a range of LE Audio-enabled use cases for earbuds, including audio sharing and broadcast, gaming mode and stereo recording. These dual-mode platforms integrate the best of LE Audio and the best of Classic Bluetooth, to enable smooth feature adoption for real-world listening scenarios.

Excellence in sound quality

QCC3071 is designed to offer a selection of options for delivering crystal-clear voice calls in earbuds. These include super wide band voice quality with Qualcomm® aptX™ Voice technology, and up to 3-microphone Qualcomm® cVc™ Echo Cancelling and Noise Suppression (ECNS).
This platform also supports both 24-bit 96kHz and 24-bit lossless audio quality in an adaptive platform, along with low-latency Bluetooth audio for gaming.

Integrated noise cancellation

QCC3071 supports our third-generation Qualcomm® Adaptive Active Noise Cancellation (ANC), which leverages an integrated, dedicated hardware block on the platform. It supports incredibly low-latency and low-power performance for noise cancellation, without taxing the audio subsystem. This tech is designed for increased bit-depth and sample rates, allowing more precise filter control so audio developers can tune for stronger noise cancellation across a wider range of frequencies.

Wide range of differentiating audio features

Differentiate at a range of consumer price points with choice from our portfolio of licensable audio technologies, including digital assistant support, Qualcomm Adaptive ANC, aptX Adaptive Audio for up to 96kHz audio resolution, aptX Voice, and cVc, and Snapdragon Sound.
