+# Concatenator
+
+A C++ application for generating granular synthesis driven representations of
+audio files based on audio database analysis.
+
+This application is under development with the aim to explore the creative
+potential of combining short-time audio analyses with granular synthesis, to
+synthesize perceptually related representations of target audio files. Through
+use of analysed databases of varying sizes, an output can be generated that
+represents a mix of the spectral and temporal features of the original target
+sound and the corpus of source sounds.
+
+To achieve this, a technique known as "concatenative synthesis" is used. This
+form of synthesis combines the ability to window and join small segments of
+sound to create a new sound (a process known as granular synthesis), with audio
+analysis techniques capable of describing a sound in order to differentiate it
+from others. By analysing small segments in a target sound for their perceptual
+characteristics (such as pitch, timbre and loudness), it is then possible to
+compare these segments to a collection of source sounds to find perceptually
+similar segments. From this, the most perceptually similar matches can be taken
+and joined using granular synthesis techniques in order to achieve the final
+result.
+
+Note: This project is currently under development and is not ready for release.
+This project is based on the pysound project developed to explore concatenative
+synthesis in Python which can be found here:
+https://github.com/Pezz89/pysound
+This project's primary goal at present is to build on the performance of
+Pysound through the higher efficiency of the C++ language and to address issues
+with packaging and distribution encountered during the development of that
+project.
