Detailed Description

Calculates the slope of the Envelope Follower.

This class caclulates the slope of the envelope using a linear regression scheme. This method was chosen over a derivative one as it is more resistant to noise. A moving window skips forward one sample at a time performing a m_numRegressionPoints linear regression to calculate the slope.
