In particular, we use the power value distribution of the samples of those kits. We do experiments on three different drum kits. As normally the snare drum is the instrument with the highest number of samples, we choose this drum for our experiments. -See Table \ref{tab:drumkit_data} for some information about the samples of the drum kits and see Figure \ref{fig:power_level_distribution} for a visualization of the power level distribution of the kits. - -\begin{table} -\caption{Drum kit data.} -\label{tab:drumkit_data} -\centering -\begin{tabular}{|l||rr|} -\hline -name & number of snare samples & \\ -\hline -DRS kit & 234 & \\ -other kit & 234 & \\ -and other kit & 234 & \\ -\hline -\end{tabular} -\end{table} +% See Table \ref{tab:drumkit_data} for some information about the samples of the drum kits and see Figure \ref{fig:power_level_distribution} for a visualization of the power level distribution of the kits. +For our experiments, we use the Crocell kit, which has 98 snare samples.
