- 例程难度：
此示例展示了如何使用 ESP-ADF 的多输入管道通过音频塑造 (audio forge) 处理播放多个音频文件。
音频塑造包含了重采样 (resample)、向下混叠 (downmix)、自动电平控制 (ALC)、均衡器 (equalizer)、变声 (sonic) 等处理过程，通过 audio_forge 的结构体成员 component_select 的掩码来组合这几个功能的选择。
此例程音频塑造的管道如下：
---> fatfs_stream ---> wav_decoder ---> raw_stream --->
| |
[sdcard] ---> (NUMBER_SOURCE_FILE) ---> audio_forge ---> i2s_stream ---> [codec_chip]
| | ▲
---> fatfs_stream ---> wav_decoder ---> raw_stream ---> |
┌───────┴────────┐
│ resample │
│ downmix │
│ ALC │
│ equalizer │
│ sonic │
└────────────────┘
本例程支持的开发板在 $ADF_PATH/examples/README_CN.md 文档中例程与乐鑫音频开发板的兼容性表格中有标注，表格中标有绿色复选框的开发板均可运行本例程。请记住，如下面的 配置 一节所述，可以在 menuconfig 中选择开发板。
本例程支持 IDF release/v5.0 及以后的分支，例程默认使用 ADF 的內建分支 $ADF_PATH/esp-idf。
本例程需要准备一张 microSD 卡以及两首 WAV 音频文件，将音频文件分别重命名为 test1.wav 和 test2.wav 并拷贝到 microSD 卡中，然后把 microSD 卡插入开发板备用，
本例程默认选择的开发板是 ESP32-Lyrat V4.3，如果需要在其他的开发板上运行此例程，则需要在 menuconfig 中选择开发板的配置，例如选择 ESP32-Lyrat-Mini V1.1。
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
如果你需要修改录音文件名，本例程建议同时打开 FatFs 长文件名支持。
menuconfig > Component config > FAT Filesystem support > Long filename support
请先编译版本并烧录到开发板上，然后运行 monitor 工具来查看串口输出 (替换 PORT 为端口名称)：
idf.py -p PORT flash monitor
退出调试界面使用 Ctrl-]。
有关配置和使用 ESP-IDF 生成项目的完整步骤，请参阅 《ESP-IDF 编程指南》。
- 例程开始运行后，等待用户按下 [Mode] 按键开始执行例程，打印如下：
