- Description:
-
-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-
- int32 xr[ ], rescaled data
- struct gr_info_s *gr_info, granule structure
- mp3Header *info, mp3 header info
- int32 Scratch_mem[198] for temporary usage
-
- Outputs:
-
- int32 xr[ ], reordered data
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- If short blocks are used (block_type[gr][ch]=='10'), the rescaled data
- xr[scf_band][window][freq_line] shall be reordered in polyphase subband
- order, xr[subband][window][freq_line], prior to the IMDCT operation.
