+sonogram~.dll : displays, plays back and lets you modify a recorded sonogram.
+
+The real and imaginery part of an fft~ is stored in a sonogram~
+and, then, you can apply modifications to it
+or do mouse-based graphic modifications.
+The set of modifications provided for now consists of
+matrix operations but it will be improved soon.
+
+To install sonogram~, follow the steps from INSTALL
