PureData 单音 FM 合成器实战：频率调制、包络控制与音色调节

PureData 是一个开源的图形编程语言，广泛应用于音频处理、音乐制作和实时音频控制等领域。本文将围绕 PureData 语言，实现一个单音 FM 合成器，通过频率调制（FM）、包络控制（ADSR）和音色调节等功能，展示如何使用 PureData 进行音频合成。

FM 合成器原理

频率调制（Frequency Modulation，简称 FM）是一种通过改变载波频率来产生音调的合成方法。在 FM 合成器中，一个高频振荡器（载波）的频率被调制器（调制信号）所控制，从而产生新的音调。

PureData 环境搭建

在开始编写代码之前，我们需要搭建一个 PureData 环境。以下是搭建步骤：

1. 下载并安装 PureData：从官方网址（https://puredata.info/downloads）下载并安装最新版本的 PureData。
2. 打开 PureData：双击桌面上的 PureData 图标，打开软件。
3. 创建新项目：在 PureData 界面中，点击“File”菜单，选择“New”创建一个新的项目。

FM 合成器代码实现

以下是一个简单的 FM 合成器代码示例，包括频率调制、包络控制和音色调节等功能。
