Part of Understanding AAC

Function Hierarchy

When FAAD2 wants to decode a SCE or LFE, this is the sequence of functions it calls in its internal hierarchy:

 syntax.c:decode_sce_lfe()
   +- syntax.c:single_lfe_channel_element()
     +- syntax.c:individual_channel_stream()
     +- (SBR decoding stuff)
     +- specrec.c:reconstruct_single_channel()

decode_sce_lfe()

single_lfe_channel_element()

single_lfe_channel_element()

individual_channel_stream(ic_stream ics)

This process is detailed in Decoding AAC CPE.
