Abstract:
1. Process for synthesis of an audio signal, named synthesized audio signal, from a sequencing signal representative of a sequence of contacts carried out on a vibrating body, said sequence comprising excitation contacts suitable for bringing the vibrating body into vibration, process in which: at least one audio signal, named audio signal of contact, is produced for each of said excitation contacts, a signal, named partial attenuation signal of remanence, is produced from a signal, named vibration signal, representative of the vibration of the vibrating body generated by at least one excitation contact, named partial contact, the partial attenuation signal of remanence being representative, for said partial contact, of at least one partial attenuation value of remanence of at least one audio signal of contact, named 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.
