docs: def seek(self, frames, whence=SEEK_SET):
          """Set the read/write position.
  
          Parameters
          ----------
          frames : int
              The frame index or offset to seek.
          whence : {SEEK_SET, SEEK_CUR, SEEK_END}, optional
              By default (``whence=SEEK_SET``), `frames` are counted from
              the beginning of the file.
              ``whence=SEEK_CUR`` seeks from the current position
              (positive and negative values are allowed for `frames`).
              ``whence=SEEK_END`` seeks from the end (use negative value
              for `frames`).
  
          Returns
          -------
          int
              The new absolute read/write position in frames.
  
          Examples
          --------
          >>> from soundfile import SoundFile, SEEK_END
          >>> myfile = SoundFile('stereo_file.wav')
  
          Seek to the beginning of the file:
  
          >>> myfile.seek(0)
          0
  
          Seek to the end of the file:
  
          >>> myfile.seek(0, SEEK_END)
          44100  # this is the file length
