enum State¶

enum State {
    Startup,
    Recording,
    Finalize,
    Done
};

Enum for tracking the state of our example process

We will begin in "startup" for a set duration, prior to recording. Then transition to recording, where the WAV file will be recorded from audio in the real time engine. After the duration of the recording has passed, we'll finalize the WAV file, and update to Done.
