        verbose (bool, optional): Flag for verbose graphs and logs. Defaults to False.
        options (list, optional): List of 3 booleans corresponding to if each corresponding step will be executed. Defaults to [True, True, True].
        sf (path, optional): Path to the SoundFont for FluidSynth. Defaults to sf_TimbresOfHeaven.
        target_eq_raw (path, optional): Path to the target EQ curve. Defaults to default_target_eq_curve.

    Returns:
        wav_path_post_eq (path): path to the wav file post synthesis.
