BRSP

Interpolation only resampling. Done in frequency domain by augmentation with zeros. No new frquencies introduced. Number of sample increases rapidly!

 brsp infile ifact tmax
 infile  =input file name 
 ifact   = resample factor ifact>=1 
         = 1 sample interval halved.  
         = 2 sample interval 1/4 of original
         = n sample interval 1/(2**n) of original
     (note: trace size increases by 2**ifact)
 tmax    =max time of output trace (float) sec
 NOTE: This is a radix 2 algorith, so trace may be 
  with zeros before computing new number of samples 
    BSEGY number of samples header is 16 bit
    Maximum number of samples limited to 32,767
