Fraunhofer’s AAC encoder software supports AAC-LC, HE-AAC, and xHE-AAC of the open international standard which is used by Google to deliver billions of hours of content to consumers worldwide. By extending this collaboration, users will be able to stream all types of content – such as movies, music, audiobooks, and podcasts.
The latest version of the AAC family, xHE-AAC, offers improved levels of coding efficiency with a usable bit rate range that spans from 12 kbit/s to 500 kbit/s and above for stereo services – helping to overcome audio bandwidth constraints and provide an enhanced and more reliable consumer experience.
Improved levels of efficiency are crucial in emerging markets where 2G/3G networks still exist in significant numbers and wherever 4G/5G networks are congested.
Audio bandwidth saved due to the increased coding efficiency can be used to improve video quality. Encoder built-in MPEG-D DRC dynamic range control and loudness metadata provide a consistent loudness level and optimal dynamic range for any playback device and environment.
