code: def mr_frequencies(tuning: float) -> Tuple[np.ndarray, np.ndarray]:
      r"""Generate center frequencies and sample rate pairs.
  
      This function will return center frequency and corresponding sample rates
      to obtain similar pitch filterbank settings as described in [#]_.
      Instead of starting with MIDI pitch `A0`, we start with `C0`.

      Parameters
      ----------
      tuning : float [scalar]
          Tuning deviation from A440, measure as a fraction of the equally
          tempered semitone (1/12 of an octave).
  
      Returns
      -------
      center_freqs : np.ndarray [shape=(n,), dtype=float]
          Center frequencies of the filter kernels.
          Also defines the number of filters in the filterbank.
      sample_rates : np.ndarray [shape=(n,), dtype=float]
          Sample rate for each filter, used for multirate filterbank.
  
      Notes
      -----
      This function caches at level 10.
