      SILK fixes following last codec WG meeting · bf75c8ec
      Koen Vos authored and Jean-Marc Valin's avatar Jean-Marc Valin committed
      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
