MLUTBox
This is a set of Matlab functions aimed at creating .cube color lookup tables starting from a reference image containing a uniform sampling of the colour space.
LabelSignal
This Matlab tool clusters the frames of an audio signal and labels the clusters with 3D coordinates that encode the similarity between the clusters as Euclidean distance. In other words, it colour-codes the timbral properties of the signal to visually represent the similarities of an audio stream.
LIM Toolbox
LIM-Toolbox is a collection of basic Matlab audio-related functions used in sound and music computing research and teaching.
