Process for synthesis of a synthesized audio signal, in which at least one audio signal of contact is produced for each excitation contact of a sequence of contacts carried out on a vibrating body (2). A partial attenuation signal of remanence is generated from at least one vibration signal representative of the vibration of the vibrating body (2) generated by at least one excitation contact, named partial contact, the partial attenuation signal of remanence being representative, of a partial attenuation of at least one remanent audio signal of contact, resulting from an excitation contact that is previous to said partial contact. The synthesized audio signal after said partial contact is produced by mixing the audio signal of contact of said partial contact and each remanent audio signal of contact affected by the partial attenuation signal of remanence. The invention extends to a device (3) for synthesizing said synthesized audio signal. The invention relates in addition, to a process and a device (3) for synthesis from a signal, named transposition signal, resulting from a sequence of contacts of changes in pitch of the vibrating body's (2) vibration. For at least one excitation contact of change in pitch, at least one frequency component, named channeled component, of an audio signal of contact, named tonal signal of contact, resulting from an excitation contact that is previous to said excitation contact of change in pitch, is modulated around a harmonic frequency of a new pitch, corresponding to a harmonic rank different from the harmonic rank of a preceding synthesis frequency of the channeled component. |
