+  Windowed Sinc FIR Generator
+  Bob Maling (BobM.DSP@gmail.com)
+  Contributed to musicdsp.org Source Code Archive
+  Last Updated: April 12, 2005
+
+  http://www.musicdsp.org/showone.php?id=194
+
+  Usage:
+    Lowpass:  wsfirLP(h, N, WINDOW, fc)
+    Highpass: wsfirHP(h, N, WINDOW, fc)
+    Bandpass: wsfirBP(h, N, WINDOW, fc1, fc2)
+    Bandstop: wsfirBS(h, N, WINDOW, fc1, fc2)
+
+  where:
+    h (float32_t[N]):  filter coefficients will be written to this array
+    N (int):    number of taps
+    WINDOW (int): Window (W_BLACKMAN, W_HANNING, or W_HAMMING)
+    fc (float32_t):  cutoff (0 < fc < 0.5, fc = f/fs)
+            --> for fs=48kHz and cutoff f=12kHz, fc = 12k/48k => 0.25
+
+    fc1 (float32_t): low cutoff (0 < fc < 0.5, fc = f/fs)
+    fc2 (float32_t): high cutoff (0 < fc < 0.5, fc = f/fs)
+
+
+  Windows included here are Blackman, Hanning, and Hamming. Other windows can be
+  added by doing the following:
+    1. "Window type constants" section: Define a global constant for the new window.
+    2. wsfirLP() function: Add the new window as a case in the switch() statement.
+    3. Create the function for the window
+
+       For windows with a design parameter, such as Kaiser, some modification
+       will be needed for each function in order to pass the parameter.
