 \section{Audio Onset Detection}
 
+\subsection{Note Onset Detector Plugin}
+
 The Note Onset Detector Vamp plugin analyses a single channel of audio and estimates the onset times of notes within the music -- that is, the times at which notes and other audible events begin.
 
 It calculates an onset likelihood function for each spectral frame, and picks peaks in a smoothed version of this function. The plugin is non-causal, returning all results at the end of processing.
 
 Please read refer to the following publication for the basic detection methods~\cite{chris2003a}. The Adaptative Whitening technique is described in~\cite{dan2007a}. The Percussion Onset detector is described in~\cite{dan2005a}.
 
+\subsection{OnsetDS Plugin}
+
+OnsetDS is an onset detector that uses Dan Stowell's OnsetsDS library\footnote{http://onsetsds.sourceforge.net/}, described in~\cite{dan2007a}.
+
+The purpose of OnsetsDS is to provide capabilities for FFT-based onset detection that works very efficiently in real-time, and can detect onsets pretty well in a broad variety of musical signals, with a fast reaction time.
+
+It is not specialised for any particular type of signal. Nor is it particularly tailored towards non-real-time use (if we were working in non-real-time there are extra things we could do to improve the precision). Its efficiency and fast reaction are designed with general real-time musical applications in mind.
