    • A method and apparatus for automatically compensating a sound volume are disclosed. The method includes the steps of determining whether a channel conversion key and an audio input switching key are inputted, producing an energy of an audio signal when the channel conversion key is inputted, and comparing an energy value of the audio signal detected for a predetermined time period with an energy value obtained from a previous step thereof and compensating for as much volume as a difference obtained by the comparison. The method together with the apparatus considers a symmetrical characteristic of an audio signal, calculates a voice energy with regard to a half signal of the audio signal, converts the calculated signal to a simplified value, and automatically compensates for the volume accordingly, thereby removing redundant manual steps.
    • 公开了一种用于自动补偿音量的方法和装置。 该方法包括以下步骤:确定是否输入频道转换键和音频输入切换键,当输入频道转换键时产生音频信号的能量,并且比较在预定时间内检测到的音频信号的能量值 周期,其具有从其前一步骤获得的能量值,并且补偿与通过比较获得的差异相同的体积。 该方法与设备一起考虑音频信号的对称特性,相对于音频信号的半信号计算语音能量,将计算出的信号转换为简化值,并相应地自动补偿音量,从而消除冗余 手动步骤。
