Abstract
A device (10) for simulating a sound timbre, particularly for stringed electrical musical instruments, which comprises means (20, 25) for acquiring an input electrical signal generated by the vibrations of the strings of a musical instrument (12, 13, 14, 15), and filtering means (50) which operate on the electrical signal generated by a source musical instrument (15). The filtering means (50) apply to the electrical signal generated by the source musical instrument (15) a transfer function obtained by correlating the sound profile (42, 43, 44) of a target musical instrument (12, 13, 14) to the sound profile (45) of the source musical instrument (15), the sound profiles (42, 43, 44, 45) comprising respectively the average frequency spectrum of a range of notes played on the target musical instrument (12, 13, 14) and the average frequency spectrum of a corresponding range of notes played on the source musical instrument (15), and the sound profiles (42, 43, 44, 45) being defined on the basis of the electrical signals generated by the musical instruments (12, 13, 14, 15), corresponding to the playing of at least one note per string, covering at least one tenth of the range of extension of the musical instruments (12, 13, 14, 15).
