     12
     13    This function reads `source_file` and creates slices, new smaller
     14    files each starting at `t` in `timestamps`, a list of integer
     15    corresponding to time locations in `source_file`, in samples.
     16
     17    If `timestamps_end` is unspecified, the slices will end at
     18    `timestamps_end[n] = timestamps[n+1]-1`, or the end of file.
     19    Otherwise, `timestamps_end` should be a list with the same length
     20    as `timestamps` containing the locations of the end of each slice.
     21
     22    If `output_dir` is unspecified, the new slices will be written in
     23    the current directory. If `output_dir` is a string, new slices
     24    will be written in `output_dir`, after creating the directory if
     25    required.
     26
     27    The default `samplerate` is 0, meaning the original sampling rate
     28    of `source_file` will be used. When using a sampling rate
     29    different to the one of the original files, `timestamps` and
     30    `timestamps_end` should be expressed in the re-sampled signal.
     31
     32    The `hopsize` parameter simply tells :class:`source` to use this
     33    hopsize and does not change the output slices.
     34
     35    If `create_first` is True and `timestamps` does not start with `0`, the
     36    first slice from `0` to `timestamps[0] - 1` will be automatically added.
     37
     38    Parameters
     39    ----------
     40    source_file : str
     41        path of the resource to slice
     42    timestamps : :obj:`list` of :obj:`int`
     43        time stamps at which to slice, in samples
     44    timestamps_end : :obj:`list` of :obj:`int` (optional)
     45        time stamps at which to end the slices
     46    output_dir : str (optional)
     47        output directory to write the slices to
     48    samplerate : int (optional)
     49        samplerate to read the file at
     50    hopsize : int (optional)
     51        number of samples read from source per iteration
     52    create_first : bool (optional)
     53        always create the slice at the start of the file
     54
     55    Examples
     56    --------
     57    Create two slices: the first slice starts at the beginning of the
     58    input file `loop.wav` and lasts exactly one second, starting at
     59    sample `0` and ending at sample `44099`; the second slice starts
     60    at sample `44100` and lasts until the end of the input file:
     61
     62    >>> aubio.slice_source_at_stamps('loop.wav', [0, 44100])
     63
     64    Create one slice, from 1 second to 2 seconds:
     65
     66    >>> aubio.slice_source_at_stamps('loop.wav', [44100], [44100 * 2 - 1])
     67
     68    Notes
     69    -----
     70    Slices may be overlapping. If `timestamps_end` is `1` element
     71    shorter than `timestamps`, the last slice will end at the end of
     72    the file.
