Crystal-clear Hi-Fi audio experiences and virtually always-on, always-listening voice assistance.

No matter what you’re listening to on your mobile device, the audio quality and interaction should be loud and clear, and retain high resolution. Qualcomm Aqstic™ audio technology on the Qualcomm® Snapdragon™ Mobile Platform is designed to deliver incredible sound quality on your device—making hearing the people and things you love better than ever.

Qualcomm Aqstic and Qualcomm Snapdragon are products of Qualcomm Technologies, Inc. and/or its subsidiaries.

How Qualcomm Aqstic audio works.

The Qualcomm Aqstic audio platform includes audio codecs, DACs, power amplifiers, and a suite of advanced audio and voice software technologies that are engineered to work together to provide the best Hi-Fi audio quality, advanced noise reduction, and voice UI experiences available on a mobile device.

Qualcomm Aqstic Voice UI

Qualcomm Aqstic voice UI technology on the Snapdragon 845 Mobile Platform makes on-device voice interaction easier than ever. It is designed to allow devices to have always-on and always-listening capabilities, giving voice-driven smart assistants improved always-on keyword detection and ultra-low power voice processing while using very little battery life, thanks to the Qualcomm Aqstic audio codec (WCD934x) and advanced voice UI software running on the Snapdragon 845 Mobile Platform.

Qualcomm Aqstic audio and voice communication suite

Advanced audio and voice communication software features

MPEG-H 3D audio

Qualcomm Aqstic MPEG-H scene-based audio supports truly immersive VR audio for 360-degree surround sound—creating a complete VR sensory experience. Higher order ambisonics (HOA) capture and play back complex sound scenes in a single scalable format, allowing for new VR experiences that were not previously possible with traditional channel and object-based audio formats.

Audio zoom

Qualcomm Aqstic audio zoom uses multiple microphones on your mobile device to focus in the intended direction you want to record, and minimizes sound coming from other directions—allowing you to concentrate on a single sound source, like in a one-on-one conversation.

Surround sound recording

Qualcomm Aqstic surround sound recording offers real 5.1 surround sound encoding using three-microphone inputs. The recorded 5.1 audio signals can be played directly through a 5.1 home theater system or on your device with a Snapdragon mobile platform for the best surround sound experience possible.

Multi-mic echo cancellation and noise suppression 

Qualcomm Aqstic multi-mic Echo Cancellation and Noise Suppression (ECNS) technology isolates noisy environments from voice signals for the clearest possible audio on phone calls.

Adaptive active noise cancellation

Qualcomm Aqstic adaptive active noise-cancellation (ANC) technology now allows for uninterrupted music and crystal-clear audio during phone calls on your battery-free active-noise-cancellation headset.
