+# libguttersynth
+This is a C port of Tom Mudd's Gutter Synth originally for Max/MSP.
+
+
+## Requirements
+* Cmake >= 2.8.12
+* Portaudio >= 2.0 for realtime example (example 3)
+
+Tested on Linux with Portaudio 2.0 version 19.
+
+## Installation
+Create a build directory at the top of the source tree, execute *cmake ..*, 
+*make* and optionally *make install* as root. If the latter is not 
+used/possible then the resulting library can be used from the build directory.
+eg:
+
+	mkdir build && cd build
+	cmake ..
+	make && sudo make install
+
+The following options can be provided to cmake.
+
+* USE_FLOAT : use single-precision floats instead of double precision. Default=OFF
+* CREATE_STATIC : create a static library in addition to shared. Default=ON
+* BUILD_EXAMPLES : build the examples in addition to library. Default=ON
+
+These are set via the -D flag and should be ON or OFF. For example to build
+with floats instead of doubles, cmake would be called with
+
+    cmake -DUSE_FLOAT=ON
+
+
+## Examples
+
+### Example 1
+Interpolates randomised parameters over 20 seconds to produce a wave file
+which has different content upon each run.
+
+### Example 2
+Demonstrates the CPP API to create a 30 second wave file in which the filters
+are randomised every second. 
+
+### Example 3
+Utilises Portaudio (if available) to demonstrate randomised output in a 
+similar fashion to example 1, but with realtime audio output.
