• Add partial_tukey and punchout_tukey apodization functions

  10 août 2014, par Martijn van Beurden

  Add partial_tukey and punchout_tukey apodization functions
  
  Adds two new apodization functions that seem to perform better than
  the apodization functions currently in the codebase and fixes three
  existing windows as well.
  
  Its important to note that this patch only affects the encoder stage
  that evaluates various possible predictors. Audio encoded with these
  new windows will still decode with existing legacy decoders.
  
  = Theory =
  These functions are used to window the  audio data at the predictor
  stage. These news functions enable the use of only part of the signal
  to generate a predictor. This helps  because short transients can
  introduce noise into the predictor. The  predictor becomes very good
  at prediciting one part of the  signal, instead of mediocre for the
  whole block.
