![]() Those technologies are also used for remote broadcasting and intrastudio connection. “We are developing audio technologies for communication systems of the future. “This is one of our major activities: to design low-latency, high-quality audio codecs, as well as surround audio coding,” Rose said. The MPEG Surround and MP3 Surround codecs aim to make 5.1 audio more accessible. Fraunhofer’s AAC Low Delay and AAC Enhanced Low Delay are state-of-the-art audio codecs designed for maximum speech and audio quality with very low coding delay. ![]() With its documented history in the development of the MP3 and AAC digital audio compression schemes, Fraunhofer IIS has followed that technology path to develop more recent standards that address the market needs for surround-sound, full-bandwidth and lossless audio in various applications. For instance, every new iPhone from Apple uses the AAC Enhanced Low Delay codec, and Android phones support MPEG Surround. ![]() Over the past two decades, more than 1000 companies have licensed audio-specific software implementations of Fraunhofer technologies, finding homes in excess of 1 billion devices globally. Mathias Rose, head of marketing communications, said that the company works by identifying and researching needed technologies, and then it develops products that, generally, are then licensed to companies wishing to incorporate them into their products. Fraunhofer IIS (Institute for Integrated Circuits) is the firm’s institute (business unit) dedicated to the advancement of audio and multimedia digital coding technologies.
