9 Years HE AAC — Technical Challenges Using an Open Standard in Real-World Applications
The technical work on creating the MPEG HE AAC standard was finished 9 years ago. Since then, the format has become very popular in specific markets and devices such as PCs and mobile phones, mainly due to its high compression efficiency.

The problems encountered and the recommended solutions are described.
