MusicExampleSource - maximum length of audio
I want to cluster large audio data (>2h) using RapidMiner GUI.
I use MusicExampleSource (from ValueSeries Plugin) for reading the audio, but obviously it can handle only very short audio samples.
When trying to load a ca. 2 min. WAV sample (44100Hz, 16-Bit, Mono --> should be approx. 5 MB in memory) I get an OutOfMemoryError (Java heap space).
What goes wrong? Why is MusicExampleSource allocating tons of memory?
How can I read in larger audio samples?
