    • There is provided a sound processing apparatus and a sound processing method which are capable of reproducing discrete data with a high-quality sound matching users' preferences. In a sound processing means 2, since an interpolation value reflecting a value of a variable parameter α by which the value of a control sampling function c0(t) is multiplied can be calculated, an analog signal obtained through the interpolation performed in a sampling function sN(t) can be regulated in accordance with the variable parameter α by changing the value of the variable parameter α. In this way, by allowing the user to appropriately change the variable parameter α in accordance with various conditions including music reproduction environments, sound sources, musical tones and so on, it becomes possible to reproduce high-quality-sound music in which its frequency characteristics of the analog signal have changed and a high quality desired by the user is obtained.
    • 提供了一种声音处理装置和声音处理方法,其能够以与用户喜好相匹配的高质量声音再现离散数据。 在声音处理装置2中,由于可以计算出反映控制采样函数c0(t)的值被乘以的可变参数αa的值的内插值,所以通过采样函数 可以通过改变可变参数α的值,根据变量参数α来调整sN(t)。 以这种方式,通过允许用户根据包括音乐再现环境,声源,音乐等的各种条件适当地改变可变参数α,可以再现高质量音乐,其中其频率特性 的模拟信号已经改变,并且获得了用户期望的高质量。
