CS48LV12 - Ultra Low Power Voice Processors Featuring SoundClear? Technology - DSP - 低功耗音频转换器 - Cirrus Logic
The CS48LV12 and CS48LV13 ultra low power voice processors provide a new standard in HD Voice performance, functionality and cost effectiveness. These ICs are a total solution for handset and hands-free communications across a wide number of multimedia platforms. Featuring SoundClear technology, these products deliver best-in-class mobile noise reduction and echo cancelation, along with superior speech recognition.
The CS48LV12 provides all the voice processing features and performance needed for today’s high end smartphone, tablet and other voice communication devices in a tiny, ultra low power package. Its integrated media processor enriches music playback through speakers and headphones with built-in virtual surround, bass enhancement, bass virtualization, multi-band compression and parametric EQ algorithms, all tunable through a simple GUI.
The CS48LV13 provides the same feature set as the CS48LV12, but adds Cirrus Logic’s ASR Enhance to improve the accuracy of any ASR (Automatic Speech Recognition) engine under noisy conditions. The CS48LV13 supports several optional features including Cirrus Logic’s proprietary voice activity detector and ASR Enhance, and Sensory's TrulyHandsfree* voice control and speaker verification to enable “always on” voice wake up of mobile devices. An expanded menu of third-party media playback algorithms from Dolby** and DTS** also can be integrated.
