c@0: %% Multichannel audio source separation evaluation framework (MASSEF) c@0: % c@0: %% Overview c@0: % c@8: % <<../MASSEF.png>> c@8: % c@0: % The multichannel audio source separation evaluation framework is designed c@9: % to facilitate the development and evaluation of audio source separation c@9: % algorithms. The framework generates the mixture(s), provides the c@9: % mixture(s) to the separation algorithm(s), and evaluates the outputs of c@9: % the separation algorithm(s). The framework can also calculate and c@9: % evaluate the ideal masks for the purposes of comparison. c@0: % c@0: % Sources may have any number of channels; the framework evaluates each c@14: % channel. The use of c@14: % objects facilitate the evaluation of spatialised mixtures (e.g. c@14: % binaural). c@0: % c@0: % The framework comprises two main classes: c@0: % c@0: % * —multichannel audio source separation c@0: % evaluation framework class. c@0: % * —the results class used by c@0: % MASSEF. c@0: % c@0: % c@0: % c@0: % MASSEF can be used to evaluate and compare binaural separation algorithms, c@0: % provided that the algorithms conform to the . c@0: % c@0: %% Installation c@0: % c@0: % Before using the framework, you need to download and install its c@0: % dependencies. This can be done automatically using the c@9: % method. Before each session, c@0: % MASSEF needs to be started using the method. c@0: % c@0: %% Usage c@0: % c@0: % The framework can be run in two ways: c@0: % c@14: % # by providing c@14: % objects and separation algorithms, or c@0: % # by providing estimate and true source wav files. c@0: % c@9: % If 1), the framework operates as described above. In addition, the c@9: % framework can: c@9: % c@9: % * evaluate localisation accuracy (if the algorithm performs localisation) c@9: % of any azimuth/elevation estimates returned by the algorithm, and c@9: % * evaluate time-frequency mask accuracy (if the algorithm calculates c@9: % one). c@9: % c@9: % Use the method to operate in c@9: % this mode. c@0: % c@0: % If 2), the framework evaluates only the supplied estimate(s) using c@9: % signal-related metrics. Use the method to operate in this mode. c@0: % c@0: % c@0: %
