1. A respiratory monitoring system, comprising:

  • a transducer;

    a processor communicatively coupled with the transducer; and

    an output interface, wherein under control of the processor the system extracts an energy envelope of an acoustic physiological signal captured by the transducer, applies a median filter and a low-pass filter in sequence to the energy envelope, and generates an estimate of a respiration parameter using the sequentially filtered energy envelope, and wherein the estimate is outputted on the output interface.
