Abstract : Audio descriptor extraction is the activity of finding mathematical models which describe properties of the sound, requiring signal processing skills. The scientific literature presents a vast collection of descriptors (e.g. energy, tempo, tonality) each one representing a significant effort of research in finding an appropriate descriptor for a particular application. The Extractor Discovery System (EDS) [1] is a recent approach for the discovery of such descriptors, which aim is to extract them automatically. This system can be useful for both non experts – who can let the system work fully automatically – and experts – who can start the system with an initial solution expecting it to enhance their results. Nevertheless, EDS still needs to be massively tested. We consider that its comparison with the results of problems already studied would be very useful to validate it as an effective tool. This work intends to perform the first part of this validation, comparing the results from classic approaches with EDS results when operated by a completely naïve user building a guitar chord recognizer.
