Meta:
Roadmap id: MMWG2011-
Headline: NEON optimisations for SBR (spectral band replication - enhances audio especially at low bit rates) and PS (parametric stereo - carries 2-3 kbit/s of side info which together with mono audio stream, allows the decoder (player) to regenerate a faithful spatial approximation of the original stereo panorama at very low bitrates)
Acceptance: FIXME
Output: FIXME
