Features
Yamaha audio codecs are optimized for mobile devices. They have low powe consumption, and use a built-in DSP to provide high quality sound from micro speakers.
They also apply audio effects to offer such functions as acoustic sound field processing.
We provide codec with voice communications quality enhancers built in, such as noise suppressors and echo cancellers that are ideal for a wide range of mobile device applications.
We also provide OS drivers for the Android OS and other operating systems.
Yamaha codecs are used primarily in mobile phones, smartphones, and a wide range of other mobile devices.
