      <p>
        When we use a FFT-PLAN for the first time, it is better to
        calculate and store a new FFT-PLAN in non-realtime with the utility
        <code>NEW-FFT-PLAN</code> as in the prior example to avoid xruns.
        The possible values for the <code>FLAGS</code> argument are
        <code>+FFT-PLAN-OPTIMAL+</code>, <code>+FFT-PLAN-BEST+</code> and
        <code>+FFT-PLAN-FAST+</code> (default).
        <code>GET-FFT-PLAN</code> returns a FFT-PLAN relat
