+# Faithful Hilbert Transform
+
+This repository implements the "hilbert transform" on a sound data stream in a faithful manner.
+The Hilbert transform is a phase shift in the frequency domain of all frequencies by 90%.
+
+The mechanism implemented here is a sliding window of Fourier transforms in which only the middle
+part contributes to the output of the transform.  This buffering/windowing, at least according
+to our tests, provides much more accurate and also more efficient Hilbert transforms than say 
+use an approximation by convolution.
+
+Enjoy.
