MPEG-4 contains mechanisms of handling the functionality of the compositor for both ‘Basic composition’ and ‘Advanced effects’. ‘Profile 1’ handles just synchronisation and routing. ‘Profile Full composition’ covers additionally mixing, tone control and sample rate conversion. ‘Profile Advanced effects’ includes reverb, spatialisation, flanging, filtering, compression, limiting, dynamic range control etc.. Profiles 1 and Full can both be handled within the system part of MPEG-4, i.e. outside the audio decoder. Profile Advanced effects is handled in the audio/SNHC compositor, the Structured Audio/Effects (SAFX) box.
