Public Methods
void	setup () throws IOException, ParserException
	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.

Member Function Documentation

EDLFile composers.VQComposer.compose (    )  [inline, virtual]

Compose an EDLFile. This is where the magic happens. Implements composers.Composer. Reimplemented in composers.HMMComposer. Definition at line 386 of file VQComposer.java. References composers.VQComposer.learnCodebook().

void composers.VQComposer.setup (    )  throws IOException, ParserException [inline]

Setup the Composer - read in files, etc. This should be called before any call to compose() to ensure that the inputs and outputs are properly initialized. Reimplemented from composers.Composer. Definition at line 168 of file VQComposer.java.
