EVS: Crystal clear and robust phone calls
Enhanced Voice Services (EVS), the state-of-the-art 3GPP/GSMA speech and audio codec, has been adopted as mandatory for Vo5G services and is already in use in VoLTE/VoWiFi services worldwide. It enables phone calls with super-wideband high-quality speech, bringing call fidelity up to the same level as today’s other digital media services – at unmatched low bit rates. Thanks to EVS’s advanced robustness against packet loss, network coverage is considerably enhanced, including indoor coverage. Stop by at our booth and experience an EVS call: it will feel like you’re in the same room with the person you’re talking to.
xHE-AAC: The latest audio codec for music and video streaming
Poor network connectivity causing audio streams to drop is a thing of the past, thanks to xHE-AAC. The latest addition to the AAC codec family offers maximum coding efficiency, with a bit rate range from 12 kbit/s to 500 kbit/s and above for stereo services. Combining this with seamless bit rate switching over DASH and HLS, and mandatory MPEG-D DRC Loudness and Dynamic Range Control, xHE-AAC is the ideal solution for adaptive audio and video streaming services – whether it’s for movies, music, audiobooks or podcasts – as well as for digital radio broadcasting. The codec is natively supported in Android 9 Pie. Come put it to the test at Fraunhofer’s MWC Shanghai booth, where we will showcase various video and Internet radio streaming applications with xHE-AAC.
Live streaming using the MPEG-H Audio system
Next-Generation Audio is already a reality with MPEG-H Audio – the audio system enabling immersive and interactive sound together with enhanced accessibility features has been on the air 24/7 in South Korea since the launch of its UHDTV system in May 2017. Experience the benefits of MPEG-H Live Streaming over HLS at our booth at MWC Shanghai 2019.
Fraunhofer upHear Immersive Audio Virtualizer: True 3D sound from just one device
In a dedicated “living room”, the Fraunhofer 3D soundbar reference design will demonstrate how to deliver cinema-style immersive sound to consumers in a convenient, high-quality fashion. At its core: the upHear Immersive Audio Virtualizer. Developed to enable the most immersive consumer experience from soundbars and TVs, the technology supports the rendering of 3D audio content as well as the upmix of legacy surround or stereo audio.
upHear Voice Quality Enhancement: Enhanced far-field voice signals for smart devices

You will also be able to check out Fraunhofer upHear Voice Quality Enhancement. This software facilitates voice-controlled human-machine interaction even at great distance to the smart device. The technology is flexible towards a wide range of microphone array geometries built into mobile phones and smart home devices such as smart speakers. upHear Voice Quality Enhancement removes interfering sounds captured by the device’s microphones, extracts the user’s voice and cancels out acoustical echoes – making it easier for the automatic speech recognizer to understand a request. Russian-based technology company Yandex has incorporated upHear Voice Quality Enhancement into its first smart speaker, enabling the device’s keyword spotter and speech recognizer to accurately hear voice commands issued from anywhere in a room, even when the speaker is playing music at the same time.
