The SoundClear Advantage
®
Cirrus Logic understands how the quality and clarity of the audio signal chain defines the total user
experience. Whether it’s a smartphone conversation in a noisy bar, listening to jazz through wireless
headphones, or watching a favorite Hollywood release on a tablet, Cirrus Logic’s patented SoundClear®
software technology delivers industry-leading voice quality, speech recognition and high-fidelity playback.
SoundClear® utilizes intelligent speech tracking and adaptive processing to exploit speech patterns and
environmental conditions, and provides advanced processing features such as noise suppression, echo
cancelation and virtual surround sound. The result is self-adjusting algorithms that emphasize voice quality,
whether in a quiet room or the noisiest vehicle. The SoundClear® algorithms also deliver consistent audio
performance with automatic microphone calibration, automatic level control and automatic volume control.
