It is easy to see that the computation of the alpha constant is slightly inefficient, as the root value can be close to 1 for the lower frequencies, which would result in significant roundoff error if this value is subtracted from 1. In this patch, the computation of the alpha, beta, and gamma constants has been simplified and refactored.
