a method for improving characteristics of acoustic and vibration transducers , including integrated microphones and integrated transducers of vibrations , is disclosed . the method consists in the use of a low - fidelity acoustic or vibration transducer for converting an acoustic signal into an analog electrical signal , an analog - to - digital converter for converting the analog electrical signal into a digital signal and a digital processor for correcting and enhancing the latter signal . the resulting digital representation of the acoustic signal is analogous to that attainable by using a high - fidelity transducer .
