James Almer 9d5e81d3b1 Revert "x86/sbrdsp: remove unnecessary sign extend instruction in apply_noise_main" 
This reverts commit 24bb7db403.

noise has to after all be sign extended, not zero extended, on tests
other than checkasm.
Fixes most aac tests broken by the now reverted commit.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • ffserver is a multimedia streaming server for live broadcasts.
