 The Cepstral Pitch Tracker Vamp Plugin is an open source Vamp plugin
 library that implements a monophonic pitch tracking and note
-segmentation method.
+segmentation method that can be used to track melodic pitch in
+accompanied vocal music.

 This plugin library is available online as a free, open source
 download from the Centre for Digital Music at Queen Mary, University
 of London. It was initially developed as an illustration of the use of

 \section{Introduction}\label{sec:introduction}

-describe vamp
-describe rationale supporting submission\ldots
+The Vamp plugin format\footnote{http://vamp-plugins.org/} was
+developed at the Centre for Digital Music (C4DM) at Queen Mary,
+University of London, during 2005-2006 and published as an open
+specification, alongside the Sonic
+Visualiser~\cite{sonicvisualise2010} audio analysis application, in
+response to a desire to publish algorithms developed at the Centre in
+a form in which they could be immediately useful to people outside
+this research field.

+In subsequent years the Vamp plugin format has become a moderately
+popular means of distributing methods from the Centre and other
+research groups. Some dozens of Vamp plugins are now available from
+groups such as the MTG at UPF in Barcelona, the SMC at INESC in Porto,
+the BBC, and others as well as from the Centre for Digital Music.
+
+The Cepstral Pitch Tracker Vamp Plugin is a freely-available, open
+source Vamp plugin implementation of a monophonic pitch tracking and
+note segmentation method.
+
+\section{Method}\label{sec:method}
+
+The method is that described in the one-page handout ``Unit Testing:
+An audio research example'' accompanying our tutorial at DAFx
+2012\cite{chris2012a}. It is an agent system consisting of five
+components:
+
+\begin{enumerate}
+\item Short-time Fourier transform;
+\item Transform to cepstral domain, as the inverse FFT of the log
+  magnitude spectrum;
+\item Peak finder and interpolator;
+\item Agent that takes a series of pitch peaks and tests to see if they form a plausible note;
+\item Agent-management system that supplies the pitches to agents;
+  creates a new agent when a novel pitch is found and reaps any agents
+  that expire without finding a plausible note; accumulates a list of
+  valid notes; and discards failures.
+\end{enumerate}
