Janata Lab Music Toolbox (jlmt)

brief description:

Briefly the jlmt is used to carry out Musical Spaces analyses within the lab.

The jlmt consists of a series of MATLAB functions for performing analyses of musical audio signals. The package is an adjunct to an extant Matlab toolbox, the IPEM Toolbox, developed for perception-based music analysis. The JLMT makes significant contributions to the IPEM toolbox by adding a flexible job manager, expanding the parameter space used to create contextuality images, generating pitch class projections and projections to toroidal space from periodicity pitch and contextuality images. It also integrates functionality from the BTB (Beyond the Beat) algorithm developed by Tomic and Janata for performing rhythm based analyses of musical audio signals and MIDI recordings of tapping responses.
