-\section{Data \& Preprocessing}
-To run the experiments we have collected data from several \gls{dm} albums. The
-exact data used is available in Appendix~\ref{app:data}. The albums are
-extracted from the audio CD and converted to a mono channel waveform with the
-correct samplerate \emph{SoX}~\footnote{\url{http://sox.sourceforge.net/}}.
-When the waveforms are finished they are converted to \glspl{MFCC} vectors
-using the \emph{python\_speech\_features}%
-~\footnote{\url{https://github.com/jameslyons/python_speech_features}} package.
-All these steps combined results in thirteen tab separated features per line in
-a file for every source file. Every file is annotated using
-Praat~\cite{boersma_praat_2002} where the utterances are manually
-aligned to the audio. An example of an utterances are shown in
-Figures~\ref{fig:bloodstained,fig:abominations}. It is clearly visible that
-within the genre of death metal there are a lot of different spectral patterns
-visible.

-The data is collected from two\todo{more in the future}\ studio albums. The first
-band is called \emph{Cannibal Corpse} and has been producing \gls{dm} for almost
-25 years and have been creating the same type every album. The singer of
-\emph{Cannibal Corpse} has a very raspy growls and the lyrics are quite
-comprehensible. The second band is called \emph{Disgorge} and make even more
-violent music. The growls of the lead singer sound more like a coffee grinder
-and are more shallow. The lyrics are completely incomprehensible and therefore
-some parts are not annotated with lyrics because it was too difficult to hear
-what was being sung.

-\section{Methods}
-\todo{To remove in final thesis}
-The initial planning is still up to date. About one and a half album has been
-annotated and a framework for setting up experiments has been created.
-Moreover, the first exploratory experiments are already been executed and
-promising. In April the experimental dataset will be expanded and I will try to
-mimic some of the experiments done in the literature to see whether it performs
-similar on Death Metal
