Keeps the sound from sounding like it is abruptly cut off. When the length of the silence is less than the keep_silence duration it is split evenly between the preceding and following non-silent segments. If True is specified, all the silence is kept, if False none is kept. default: 100ms seek_step - step size for interating over the segment in ms c�p�tj|��\}}t|d��t||��S)z$s -> (s0,s1), (s1,s2), (s2, s3), ...N)r�tee�next�zip)�iterable�a�bs r �pairwisez"split_on_silence.<locals>.pairwise�s0��}�X�&�&��1��Q�� 1�a�y�y�r"rc�*��g|]\}}|�z |�zg��S�r5)�.0�start�end�keep_silences �r � <listcomp>z$split_on_silence.<locals>.<listcomp>�s<��U�3��,� ��l� 2�4��r"r�c �|��g|]8\}}�t|d��t|t��9S)r)�max�minr)r6r7r8rs �r r:z$split_on_silence.<locals>.<listcomp>�sQ��E�#� �s�5��|�|�c�#�c�-�.@�.@�&A�&A�A�C��r")� isinstance�boolrr))rrrr9rr3� output_ranges�range_i�range_ii�last_end� next_starts` ` r �split_on_silencerFps��4��,��%�%�A�-9�@�s�=�)�)�)�q�� PY�Z�Z��M�&�X�m�4�4�%�%��1�:��a�[� �� "�:�-��1�G�A�J�!�!�*�H�Q�K��&��r"�I�� c��d}|dksJ�||||z�j|krA|t|��kr.||z }||||z�j|kr|t|��k�.t|t|��S)a Returns the millisecond/index that the leading silence ends. audio_segment - the segment to find silence in silence_threshold - the upper bound for how quiet is silent in dFBS chunk_size - chunk size for interating over the segment in ms r)�dBFSrr>)�sound�silence_threshold� chunk_size�trim_mss r �detect_leading_silencerO�s��G��>�>�>�>� �� *�*� +� 0�3D� D� D��SV�W\�S]�S]�I]�I]��:�� *�*� +� 0�3D� D� D��SV�W\�S]�S]�I]�I]��w��E� � �#�#�#r")rrr)rrr*r)rGrH)�__doc__r�utilsrr!r)rFrOr5r"r �<module>rRs��@�@�@�@�F!�!�!�!�H\_� �3�3�3�3�l$�$�$�$�$�$r"
