    摘要: The invention provides a sound processing device. In one embodiment, the sound processing device comprises a first microphone, a first analog-to-digital converter, a second microphone, and a second analog-to-digital converter. The first microphone detects a first sound pressure to generate a first analog audio signal. The first analog-to-digital converter converts the first analog audio signal to a first digital audio signal. The second microphone detects a second sound pressure to generate a second analog audio signal. The second analog-to-digital converter converts the second analog audio signal to a second digital audio signal, encodes a third digital audio signal according to the second digital audio signal, receives the first digital audio signal and a clock signal, outputs data bits of the third digital audio signal when the clock signal oscillates to a logic low level, and outputs data bits of the first digital audio signal when the clock signal oscillates to a logic high level.

    摘要: A D/A conversion method and D/A converter. First, an m-bit data is input, wherein the m-bit data includes upper n bit data and lower m−n bit data. Then, a first n bit data is obtained by transforming the upper n bit data. Finally, the upper n bit data is applied to an n-bit D/A converter for a first duration and the first n-bit data is applied to the n-bit D/A converter for a second duration, according- to the lower m−n bit data.
