Abstract

An electronic device and gain control method. The gain control method includes the following steps: receiving a sound signal; calculating the volume according to each value of the sound signal in the past period; determining a gain value based on the volume; and using the gain value to amplify the sound signal, and then storing the sound signal.

Description

technical field [0001] The invention relates to an electronic device and method for processing sound signals, and in particular to an electronic device and a gain control method. Background technique [0002] Nowadays, many consumer electronic devices have broadcasting and recording functions. The above-mentioned broadcasting is inevitably affected by the environment. For example, the sound level may be too high in a quiet environment, and may be too low in a noisy environment. [0003] The above-mentioned recording function may encounter extremely low or extremely high volume, for example, the volume of ordinary people's speech is very low, while the volume of a concert is very loud. Current consumer electronic devices will amplify the sound signal to a preset target level regardless of the volume of the received sound signal when recording, but the real volume will always vary and will not remain at the same level. same level. Such a recording function loses the dynamic ...
