Method And System For Commanding The Production Of An Acoustic Waveform Based On A Physiological Control Signal, And Associated Computer Program

The method for commanding the production of an acoustic waveform based on a physiological control signal, includes: one provides sampled sound data including S sound samples stored on a data carrier; repeatedly, for n successive respective time intervals [t_n; t_n+1[ between an initial time t_aand a final time t_b: one provides a physiological control signal phi(t) as a function of time, during the current time interval [t_n; t_n+1[; a rate determination module of a processor determines a rate r_nof samples to be played during that time interval based on a value phi (t_n) of the physiological control signal at time t_n; a command module of the processor commands the play of a part of the acoustic waveform from the sampled sound data as a function of the determined rate r_nof samples.

1. Method for commanding the production of an acoustic waveform based on a physiological control signal, comprising: providing sampled sound data comprising S sound samples stored on a data carrier, repeatedly, for n successive respective time intervals [t_n; t_n+1[ between an initial time t_aand a final time t_b: providing a physiological control signal phi(t) as a function of time, during the current time interval [t_n; t_n+1[, a rate determination module (13) of a processor determines a rate r_nof samples to be played during that time interval based on a value phi (t_n) of the physiological control signal at time t_n, a command module (15) of the processor commands the play of a part of the acoustic waveform from the sampled sound data as a function of the determined rate r_nof samples.
14. System for commanding the production of an acoustic waveform based on a physiological control signal, comprising: a data carrier storing sampled sound data comprising S sound samples, a processor configured to repeatedly, for n successive respective time intervals [t_n; t_n+1[ between the initial time t_aand the final time t_b: a physiological control signal phi(t) being provided as a function of time, during the current time interval [t_n; t_n+1[, determine a rate r_nof samples to be played during that time interval based on a value phi (t_n) of the physiological control signal at time t_n, using a rate determination module (13) of the processor, command the play of a part of the acoustic waveform from the sampled sound data as a function of the determined rate r_nof samples, using a command module (15) of the processor.
