bb1e78a118 Fix checks for {Front,Side,Back}ElementIsCpe
{Front,Side,Back}ElementIsCpe is an array (per-channel). The check for
pPce->{Front,Side,Back}ElementIsCpe without an index checks the address
of the array, and will always evaluate to true. The elTagSce++
statements are unreachable.

d52f374768 Move back to C++98.
This code depends on narrowing hex literals to a signed long, which
trips -Wc++11-narrowing (the fix would be to explicitly cast each
value to signed).

6792cf6361 AAC-Decoder: SBR delay for gapless
Revise decoder output delay determination. The output delay consisted of
  concealment and limiter delay. SBR delay was not covered but must be
  considered for gapless playback delay compensation.

603f48ab99 AAC Decoder: introduce time domain limiter
Introduce time domain limiter. The module is per default enabled for all
  AAC-LC and HE-AAC v1/2 streams. For all ER-AAC-LD and ER-AAC-ELD streams
  the limiter is disabled per default. The feature can be en- or disabled
  via dynamic API parameter. Note that the limiter introduces an additional
  output delay which depends on the module parameters and the streams
  sampling rate.

f2f96fb86d AArch64: Make LONG 4 bytes
The libSYS/include/machine_type.h header file states LONG should be
"Data type representing 4 byte signed integer on all supported
platforms" but only provided for defining LONG as INT and ULONG as
UINT when __x86_64__ was defined. This has been changed to when
__LP64__ is defined, so that it also applies to AArch64. The change
to libFDK/include/common_fix.h is then needed to get the project to
compile.

ed247dfa54 Encoder quantizer fix
AAC Encoder: Saturate quantizer shift value to prevent
  undefined behaviour.

In very rare cases the shift value 'totalShift = (16-4)-(3*(totalShift>>2))'
 can be greater than accu data width. If you apply a shift with more then
 31 bit the result depends on the architecture and is not defined in C.
For certain platforms zeros are shifted in. That would be our desired behaviour.
On other platforms the shift will be applied as modulo. For example >>34
 would be applied as >>2. To prevent this discrepancy the shift value
 is limited/saturated to DFRACT_BITS-1. 'accu >>= fixMin(totalShift,DFRACT_BITS-1)'.

577fcbb570 Decode and SYS lib cleanup
* AAC-Encoder

   - Remove source snippets related to unsupported frame length of 960.
   - Adjust minBits initialization for disabled VBR configuration.
     Modified file(s):
        libAACenc/src/aacenc.h
        libAACenc/src/aacenc_lib.cpp
        libAACenc/src/aacenc_tns.cpp
        libAACenc/src/bandwidth.cpp
        libAACenc/src/psy_const.h
        libAACenc/src/transform.h

   - Revise encoder parameter restrictions: "Error Resilient(ER) AAC Low Complexity"
     is not supported. Where the AAC part of the FDK encoder threw an
     initialization error, now the aacEncoder_SetParam() returns an error
     before initialization if the application tries to configure this
     audio object type.

6ab36997af Bug 7170947 Update AAC codec
From Fraunhofer:
* AAC Decoder

   - Stick to the written MPEG standard instead of the MPEG reference software
     in terms of reference level normalization. Always set the program reference
     level equal to the target level. This disables level normalization using a
     default level for streams without embedded metadata.
     Modified file(s):
        libAACdec\src\aacdec_drc.cpp

   - Fix downmix channel assignment when using a WAV output channel ordering.
     Modified file(s):
        libPCMutils\src\pcmutils_lib.cpp

   - Retain signal accuracy and prevent LSB alteration when no level correction
     needs to be done.
     Modified file(s):

        libSBRdec\src\sbr_dec.cpp
        libSBRdec\src\sbrdec_drc.cpp

   - Align metadata processing with reference implementation.

        libFDK\include\clz.h
     Added file(s):
        libFDK\include\x86\clz_x86.h

34ce250e90 Don't zero out spec coeffs before doing the final IMDCT.
Addresses bug 7140347.

When flushing the decoder, you need to make sure to zero out any
lingering spectral coefficients as well as zero out the overlap buffer
state after decoding the final access unit.  Zeroing out the spec
coefficients *before* you decode the last block, however, seems like a
mistake.  If the final block contains any useful information for the
stream, then you end up outputting the overlap portion of the second
to last decoded block combined with zeros.  Because of the shape of
the second to last block's windows, this results in what appears to be
a fade out, but actually is a zero'ed out final block.
