HE AAC is the next generation equivalent to MP3Pro. In other words it’s an optimized audio compression mode for low bitrates, such as portable player or internet usage. It is sometimes referred as AAC SBR or AAC+. The SBR stands for Spectral Bandwidth Replication. It is an audio enhancement technology designed especially for low bitrate audio and speech codecs.
This open source code release is a marketing move from Ahead Software, which is preparing for the Nero Digital launch as a part of Nero Burning ROM v6. Many audio player softwares have AAC support based on the FAAD decoder, so with this release Ahead is extending the support for their upcoming encoder in a snap.
