算機/计算机 can’t read continuous 信号 Instead they need 数字 blocks of 信息 which they can 过程
声波 波 共鸣 in the air are continuous 流 of 信息 Therefore for 算機/计算机 to be able to 理解 声波 波 信息 they need to convert this continuous 信号 into blocks of 信息 which they can 过程
模拟 to 数字 converters ADC 变形 continuous 声波 波 信息 into 数字 chunks
They do this by taking a snapshots of the 声波 波 at a specified 率 The more chunks that the 算機/计算机 store every second gives a more accurate picture of the 声波 波
用 视觉 例如 OF FRAME 率 TO 证明 THIS 概念
处理 the Information
The 数字 信息 held about 声 can be processed and transformed in ways that 模拟 信号 cannot This has allowed composers to do much more 复杂 声波 变形 and to 作品 with 声 in an almost unlimited fashion
One key advantage in having 声波 信息 储存 数字 is that it can be copied transferred duplicated and rewritten without any 损失 in 品质
