      Fix common misspellings · 6d9c16d1
      Philip Jägenstedt authored
      I stumbled upon the typo in README.draft, so took the opportunity to
      grep for common misspellings using List_of_common_misspellings.txt for
      hunspell.

      SILK fixes following last codec WG meeting · bf75c8ec
      Koen Vos authored
      decoder:
      - fixed incorrect scaling of filter states for the smallest quantization
        step sizes
      - NLSF2A now limits the prediction gain of LPC filters
      
      encoder:
      - increased damping of LTP coefficients in LTP analysis
      - increased white noise fraction in noise shaping LPC analysis
      - introduced maximum total prediction gain.  Used by Burg's method to
        exit early if prediction gain is exceeded.  This improves packet
        loss robustness and numerical robustness in Burg's method
      - Prefiltered signal is now in int32 Q10 domain, from int16 Q0
      - Increased max number of iterations in CBR gain control loop from 5 to 6
      - Removed useless code from LTP scaling control
      - Optimization: smarter LPC loop unrolling
      - Switched default win32 compile mode to be floating-point
      
      resampler:
      - made resampler have constant delay of 0.75 ms; removed delay
        compensation from silk code.
      - removed obsolete table entries (~850 Bytes)
      - increased downsampling filter order from 16 to 18/24/36 (depending on
        frequency ratio)
      - reoptimized filter coefficients

      Implements hard CBR for SILK · 294bfec2
      Jean-Marc Valin authored
      This is achieved by running the encoding process in a loop and
      padding when we don't reach the exact rate. It also implements
      VBR-with-cap, which means we no longer need to artificially decrease
      the SILK bandwidth when it's close to the cap.

      Fix the side frame conditional coding rules. · 53cc1a03
      Timothy B. Terriberry authored
      b24e5746 introduced changes to LastGainIndex which broke
       conditional coding for side frames after a mid-only frame (i.e.,
       in a 60 ms frame where the side is coded, not coded, then coded
       again).
      These rules were a mess in general, however, because the side
       channel state kept a different nFramesDecoded count from the mid
       channel state, and had no way to tell if the prior side frame was
       coded.
      
      This patch attempts to rationalize them by moving the conditional
       coding decision up to the top level, where all this information is
       available.
      The first coded side frame after an uncoded side frame now always
       uses independent coding.
      If such a frame is also not the first side frame in an Opus frame,
       then it doesn't include an LTP scaling parameter (because the LTP
       state is well-defined).

      Fixes a stereo rate mismatch bug · 3120e225
      Jean-Marc Valin authored
      This is a tentative fix for a bug found in fuzzing where the encoder
      switched from mono to stereo while in the process of changing bandwidth.
      The result was that the newly added side would use the new sampling
      rate, while the mid hadn't switched yet, causing an encoder/decoder
      mismatch. The fix is that the side rate selection gets overridden
      to use the mid rate.
      The bug would occur when compiling with fuzzing enabled and using:
      ./test_opus 0 48000 2 24000 input.sw output.sw
