InputMixer Example Compile Issue

[zlbrown77]

I'm having issues compiling the streams-generator_inputmixer-audiokit. https://github.com/pschatzmann/arduino-audio-tools/blob/main/examples/examples-audiokit/streams-generator_inputmixer-audiokit/streams-generator_inputmixer-audiokit.ino

I use the example as-is, and have tried PlatformIO, Arduino Version: 2.2.1 for Windows, Arduino Version 2.2.1 for Mac and all have returned the same error while trying to compile.

This is the error from the Arduino IDE:
