The invention relates to a method for the decomposition of an audio signal having a general form that can be expressed as x(t) = x 0 + ? 1cos(F(t)), in which F(t) is the phase of the signal, characterised in that it comprises steps consisting in determining (21) an expression of the phase equation, formula (I), and determining (21) an expression of the phase F(t) as a function of parameters measuring the anharmonicity of the signal and the morphology thereof from functions pcosn and psinn defined by formula (II). |
