12 generates smooth speech at speed up factors as high as 6X, possibly more.  It is
14 regardless of the speed up or slow down factor.  For speeding up speech by 2X or
17     newSamples = period/(speed - 1.0)
21 pitch estimator, and speed is the speedup factor.  If the current position in
30 For speed factors < 2X, the PICOLA algorithm is used.  The above
31 algorithm is first used to double the speed of one pitch period.  Then, enough
33 speed up facter, where 1.0 < speed < 2.0.  The amount of data copied is derived:
35     speed = (2*period + length)/(period + length)
36     speed*length + speed*period = 2*period + length
37     length(speed - 1) = 2*period - speed*period
38     length = period*(2 - speed)/(speed - 1)
40 For slowing down speech where 0.5 < speed < 1.0, a pitch period is inserted into
42 until the output desired speed is reached.  The length of data copied is:
44     length = period*(speed - 0.5)/(1 - speed)
47 similar to high speed factors is used.
