Before Change

        for track in T:
            self.tracks.append(track.astype(np.float32))
            self.curr_pos += track.shape[0]
            self.offsets.append(np.array([self.curr_pos]).astype(np.int64))

    def read_track(self):
         read one track each time

After Change

         write many tracks together
        

        self.tracks.resize(self.tracks.shape[0] + tracks._data.shape[0],
                           axis=0)
        self.tracks[-tracks._data.shape[0]:] = tracks._data

        self.offsets.resize(self.offsets.shape[0] + tracks._offsets.shape[0],
                            axis=0)
