PlatformIO

1. Create a new PlatformIO project: Select the Arduino framework and the correct board type. For the regular AudioKit or LyraT boards select Espressif ESP32 Dev Module as board type.
2. Add the following lines to your platformio.ini file:

lib_deps = https://github.com/pschatzmann/arduino-audiokit-hal
lib_ldf_mode = deep+
build_flags = -DAUDIOKIT_BOARD=5 
monitor_speed = 115200

3. Correct the -DAUDIOKIT_BOARD above for the board you are using. The full list of the supported boards and settings can be found in AudioKitSettings.h. For example, to use a LyraT v4.3 board (AUDIOKIT_BOARD type 1), edit -DAUDIOKIT_BOARD=5 to -DAUDIOKIT_BOARD=1. You don’t need to make the changes in the AudioKitSettings.h file itself. Please note that you can handle any other settings (e.g. ES8388_DEFAULT_INPUT_GAIN) in the same way.
4. Create your sketch in main.cpp.
5. Compile and upload
