Logic for modulating entrainment sequence with biofeedback

A wearable audio device, comprising:

• at least one biosensor for measuring a current breathing period of a user wearing the wearable audio device, wherein a breathing period is an amount of time from a beginning of one inhale to an end of a next exhale;
• at least one speaker configured to output a guiding stimulus, wherein the guiding stimulus is configured to alter the current breathing period towards a final breathing period over an interval of time at a non-linear prescribed rate, the non-linear prescribed rate being a non-linear decay;
• and
• a processing unit configured to:
• select the final breathing period;
• determine a difference between a target breathing period and the current breathing period, wherein the target breathing period is the breathing period the user should be at along the non-linear prescribed rate at a certain point of time;
• and
• adjust the guiding stimulus based at least in part on the difference between the target breathing period and the current breathing period.
