Abstract : The presentation covers all meta data extraction aspects in BpmDj. It starts with explaining different techniques to measure tempo (energy enveloppe spectra, autocorrelation, peak detectors, ray-shooting and realtime tempo extraction). Beatgraphs are introduced, spectrum measurement based on the psychoacoustic bark scale is covered as well as echo characteristic, rythm and composition extraction. SVD / PCA analysis is used to map a multidimensional spectrum space to 3 primary colors.
