Vectorbased envelope follower
Name  Type  Opt  Description 

vectorsize  int  opt  The argument is the vector size for the operation. It defaults to 512, but should be set appropriately for the size of the vectors you feed into the vectral~ object. 
clear  Clears object's sample memory (in case of a blowup).  
deltaclip  limitsofchange (2 floats) [list] 
In left inlet: The word deltaclip~ object.  , followed by two floats, limits the change in bins of successive vectors to the values given. This is equivalent to the timedomain
rampsmooth  numberofinterpolatingframes [list] 
In left inlet: The word rampsmooth~ object.  , followed by two ints, causes the vector to be smoothed in a linear fashion across successive frames. The arguments specify the number of frames to use to interpolate values in both directions. This is equivalent to the timedomain filtering done by the
signal  In left inlet: Accepts a sync signal for the output index of the vector. This is typically in the range of 0 to n1 where n is the size of the vector. In middle inlet: A sync signal received in the middle inlet is used to synchronize the input index of the vector being processed. The sync signal will typically be in the range 0 to n1 where n is the size of the vector. If the range of the sync signal is different than the output index, the incoming vector will be "binshifted" by the difference between the two signals. In right inlet: Signal data to be filtered. This will usually be frequencydomain information such as the output of an fft~ or fftin~ object. 

size  vectorsize [int] 
In left inlet: The word  , followed by a number, sets the vector size for the operation. The default is 512.
slide  slidedenominatorcoefficients (2 floats) [list] 
In left inlet: The word vectral~ to do logarithmic interpolation of successive vectors in a manner equivalent to the timedomain slide~ object. The two arguments determine the denominator coefficient for the amount of the slide.  , followed by two floats, causes
