8 years ago This is normal. By default, LPC output is a 9 dimension vector it gets flattened into 9 different (officially independent) dimensions in the resulting output as Weka does not support multidimensional features. Right now you are using per window (i.e. first 6 windows were jazz, the next 6 pop, etc.) You probably meant per-file which is a different setting. This requires aggregators.
Keep in mind there is was a breach that has damaged the original jAudio project. The project is on hold while I sort through the legal and technical complications in restoring the project.

I am trying to train an audio classifier. When I try to save as arff format it saves more attributes which were mentioned via GUI. Here is a sample output.I am using jAudio-1.0.4. Any help on this matter really appreciated.
