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 [tn; tn+1[ between an initial time ta and a final time tb: one provides a physiological control signal phi(t) as a function of time, during the current time interval [tn; tn+1[; a rate determination module of a processor determines a rate rn of samples to be played during that time interval based on a value phi (tn) of the physiological control signal at time tn; 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 rn of 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 [tn; tn+1[ between an initial time ta and a final time tb:
providing a physiological control signal phi(t) as a function of time, during the current time interval [tn; tn+1[,
a rate determination module (13) of a processor determines a rate rn of samples to be played during that time interval based on a value phi (tn) of the physiological control signal at time tn,
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 rn of 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 [tn; tn+1[ between the initial time ta and the final time tb:
a physiological control signal phi(t) being provided as a function of time, during the current time interval [tn; tn+1[,
determine a rate rn of samples to be played during that time interval based on a value phi (tn) of the physiological control signal at time tn, 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 rn of samples, using a command module (15) of the processor.
