The industry is abuzz with speculation about the upcoming video standard in ATSC 3.0, possibly including High Dynamic Range, multiple frame rates, and wider color gamuts. But the audio component of th
Fraunhofer IIS Introduces New Test Service and Trademark Program for xHE-AAC Audio Codec
Fraunhofer IIS, an institute of Fraunhofer-Gesellschaft in Germany, has announced a new web-based test service that developers and manufacturers can use to validate their implementations of the xHE-AAC audio codec for compliance with MPEG standards. The service, which is available exclusively at https://test.xhe-aac.com, is free to use upon registration with Fraunhofer IIS and will test both encoders and decoders.
xHE-AAC introduces many additional features such as mandatory loudness normalization, dynamic range control, and immediate playout frames for seamless bit rate switching that are not fully covered in MPEG conformance tests. The test service provides an easy way to further validate implementations of xHE-AAC for these advanced features, as well as testing general coding tools.
