QUOTE The Helix Fixed-point HE-AAC decoder provides an optimized 32-bit fixed-point implementation, which will be dual-licensed under RCSL/RPSL. No extra copyright license is required beyond the standard Helix license terms, although patent licenses are not included and must be acquired from the appropriate AAC licensors. The Helix AAC decoder is highly optimized for ARM processors and meets or exceeds the performance of other commercial implementations. It also features one of the first widely available fixed-point implementations of SBR. The following features are currently supported: · MPEG-2 and MPEG-4 low complexity decoding (intensity stereo, MS, TNS, PNS) · spectral band replication (SBR), high-quality mode · mono, stereo, and multichannel modes · ADTS, ADIF, and raw data block decoding · MP4, RM, and other file formats supported via Helix client https://datatype.helixcommunity.org/2005/aacfixptdec -------------------- Sr. Codec Engineer (video) \| RealNetworks Codec Group \| helixcommunity.org This information is provided "AS IS" with no warranties, grants no rights, and reflects my personal opinion.
