      Move back to C++98. · d52f3747
      Dan Albert authored
      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).

      AAC-Decoder: SBR delay for gapless · 6792cf63
      Jean-Michel Trivi authored
      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.

      AAC Decoder: introduce time domain limiter · 603f48ab
      Jean-Michel Trivi authored
      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.

      AArch64: Make LONG 4 bytes · f2f96fb8
      Marcus Oakland authored
      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.
