 Setup the Composer - read in files, etc.

EDLFile compose ()
 Compose an EDLFile.

Static Public Attributes

String description = "VQComposer trains a vector quantizer on the chunks in the input file. It then uses it to quantize the chunks in another file. For best results use the beat segmenter so each chunk has roughly the same length."

Protected Methods

void learnCodebook (FeatFile trainFile)
 Use the LBG splitting algorithm to learn a VQ codebook.
