Crystal-clear Hi-Fi audio experiences, brought to you by Qualcomm Aqstic.

Whether you’re listening to your favorite band, talking with your best friend across the globe or entering a virtual world, the sound quality on your mobile device should be loud while retaining 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.

How Qualcomm Aqstic audio works.

It can be difficult to achieve the right quality sound on smartphones. But the Qualcomm Aqstic audio engine includes a discrete audio codec, power amplifier 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 interaction experiences available on a mobile device.

Qualcomm Aqstic hardware.

Advanced audio codec

Developed by an audio technology leader, Qualcomm Aqstic audio codec (WCD 9340/9341) supports high-resolution standards that recording studios use to master tracks, creating a pure audiophile listening experience. It has an integrated DAC (digital-to-analog converter) that supports native Direct-Stream Digital (DSD) and pulse-code modulation (PCM) Hi-Fi audio playback. DSD is a standard found on Super Audio Compact Discs (SACDs), and the Qualcomm Aqstic audio codec can decode DSD files natively. The DAC on the Qualcomm Aqstic codec has ultra-low Total Harmonic Distortion plus Noise (THD+N), which means no additional noise or signal is added for the most authentic sound reproduction. The Qualcomm Aqstic codec is also designed to give you the highest dynamic range available, so you can feel the dramatic change of volume and emotion in your favorite music.

Smart speaker amplifier

The Qualcomm Aqstic speaker amplifier (WSA8810/8815) is a small chip with big sound—engineered to deliver up to 4W of Class-D power to your external speakers without having to worry about speaker damage. The wide dynamic range and low noise floor on the smart speaker power amplifier (PA) allows music to be heard loud and clear. And Speaker Protection technology helps to shield your speakers from damage when delivering volume levels that are louder than the normal range.

Advanced audio and voice software.

Immersive VR audio

MPEG-H 3D audio

Qualcomm Aqstic MPEG-H scene-based audio supports truly immersive VR audio. It is designed to allow your ears to hear 360 degrees around you as if you’re truly there, making spatial audio a critical part of a complete VR sensory experience. MPEG-H scene-based audio uses higher order ambisonics (HOA) to capture and playback complex sound scenes in a single scalable format, allowing new VR experiences that were not previously possible with traditional channel and object-based audio formats.

Recording

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 focus 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 recording using three-microphone surround sound record (SSR) inputs. The recorded 5.1 audio signals can be played directly through a 5.1 home theater system or even on your device with Snapdragon, providing the best surround sound experience possible.

Voice activation

Qualcomm Aqstic voice activation technologies are addressing the proliferation of voice UI with cutting edge technologies and platforms engineered to provide low-power, always-on and always-listening voice activation.

Active noise cancellation

Qualcomm Aqstic active-noise-cancellation technology now makes experiencing uninterrupted music and crystal-clear audio during phone calls possible on your battery-free active-noise-cancellation headset.
