In 2026, AWS MediaConvert incorporated the Fraunhofer xHE-AAC codec, offering improved audio fidelity at reduced bitrates compared to traditional AAC formats. This codec adapts in real-time to network conditions, enhancing listening experiences for podcasts, audiobooks, broadcasts, and music streaming.
Key features include advanced loudness and dynamic range control, IPF frame support facilitating seamless bitrate switching for DASH/HLS streaming, and broad bitrate coverage from 12 to over 320 kb/s stereo. This integration targets better reception quality and operational cost reductions, though performance details rely on vendor specifications.
