        Parameters
        ----------
        encoded : np.ndarray, shape=(n_frames, m)
            Frame-level annotation encodings as produced by ``encode_events``.

            Real-valued inputs are thresholded at 0.5.

        Returns
        -------
        [(time, value)] : iterable of tuples
            where `time` is the event time and `value` is an
            np.ndarray, shape=(m,) of the encoded value at that time
