Description

Advanced Audio Devices AK4962
VELVET SOUNDAudio2Go The AK4962 is the new, higher performing solution of the AK4961 that has been adopted by many portable audio products mainly smartphones since it was launched in 2014. The AK4962 enhances high quality sound technologies of the AK4961 and has newly added digital active noise cancelling function.The AK4962 is a high performance with incredible sound quality audio CODEC for portable devices based on AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. For sound processing, the AK4962 is capable of various functions for mobile applications reducing the load to the main processor while improving battery consumption. The AK4962 provides clear sound experiences even in a noisy environment with a headphone that have microphones for noise collecting. This function works as digital compensations, realizing more efficient noise cancelling when compared to traditional analog implementation.
