计算机 can’t read continuous 信号 Instead they need 数字 blocks of 信息 which they can 过程

声音 波 共鸣 in the air are continuous 流 of 信息 Therefore for 计算机 to be able to 理解 声音 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 声音 波 信息 into 数字 chunks

They do this by taking a snapshots of the 声音 波 at a specified 率 The more chunks that the 计算机 store every second gives a more accurate picture of the 声音 波

使用 视觉 例如 OF FRAME 率 TO 证明 THIS 概念

处理 the Information
The 数字 信息 held about 声音 can be processed and transformed in ways that 模拟 信号 cannot This has allowed 作曲者 to do much more 复（杂） 声音 变形 and to 作品 with 声音 in an almost unlimited fashion

One key advantage in having 声音 信息 储存 数字 is that it can be copied transferred duplicated and rewritten without any 损失 in 品质
