Abstract
An electronic device and a corresponding gain controlling method are provided. The gain controlling method includes the steps of receiving a sound signal, calculating a sound level according to each value of the sound signal in a past period, determining a gain value according to the sound level, using the gain value to amplify the sound signal, and then storing the sound signal.
Claims25
An electronic device, comprising:
- a microphone, receiving a first sound signal;
- an analog-to-digital converter, coupled to the microphone and converting the first sound signal from analog signal into digital signal;
- and
- a first processor, coupled to the analog-to-digital converter, calculating a first sound level according to each value of the first sound signal in a first past period, determining a first gain value according to the first sound level, using the first gain value to amplify the first sound signal and then storing the first sound signal.
