Abstract

In this contribution, an automatic system of song edition for Guitar Hero/Frets on Fire is presented. The system performs three fundamental stages: time analysis, frequency analysis and button allocation. The temporal analysis of the musical signal is used to obtain the rhythmic pattern of the song. The frequency analysis is perform on the basis of aMel filter bank because these filters provide an approximation to the human perception of low and high frequency sounds. The allocation of buttons is done using the rhythmic pattern extracted, the Mel filters outputs and, also, taking into account a selectable difficulty level. The distributions of the buttons obtained with the designed system are similar to the ones found in the pre-determined songs of the games.
