摘要：
An effect adding method, includes: applying (12) different gains to a positive side waveform portion and a negative side waveform portion of an audio signal respectively when absolute values of input levels of the positive side waveform portion and the negative side waveform portion are smaller than a predetermined value; producing (40) a higher range component of the audio signal based on a high range component of the audio signal to which the gain is applied, the higher range component being higher in frequency than the high range component; producing (52) a lower range component of the audio signal based on a low range component of the audio signal to which the gain is applied, the lower range component being lower in the frequency than the low range component; and synthesizing (94) an audio signal having an effect sound by adding the audio signal to which the different gains are applied, the higher range component, and the lower range component with each other.
摘要（中）：
的效果增加方法，包括：将（12）不同的增益为正侧波形部分和音频信号的负侧波形部分分别当正侧波形部分的输入电平与负侧波形部分的绝对值较小 大于一预定值; 产生（40）的基础上对音频信号被施加时，更高范围分量是频率比所述高范围分量的更高增益的高频组分的音频信号的更高范围分量; 产生（52）的基础上对音频信号被施加，较低范围分量是频率比低范围分量的低增益的低范围分量的音频信号的低范围分量; 合成和（94）具有通过将所述音频信号以其中不同的增益应用，较高的范围分量，并且与海誓山盟较低范围分量来实现声音的音频信号。
