Summary: | The invention provides an acoustic capture device and a method thereof. The acoustic capture device includes an acoustic transducer, an acoustic detector, an analog-to-digital converter, and a processing element. The acoustic transducer captures an acoustic wave to generate an analog signal. The acoustic detector detects, according to the analog signal, a specific event to generate a trigger signal. The analog-to-digital converter converts the analog signal to generate a digital signal. The processing element receives the trigger signal to execute a control process. The control process includes: analyzing the digital signal to determine ambient information; determining a first set of parameters of the acoustic detector according to the ambient information; performing a control information protocol to adjust the acoustic detector according to the first set of parameters; and performing, according to the ambient information, an enhancement processing on the digital signal to generate an enhanced digital signal. |
