  • Added: audinterface.Segment.process_table(), that segments a dataframe or series and expands its row values to the new segments

  • Added: support for numpy 2.0

  • Changed: depend on audmath>=1.4.1

Version 1.2.1 (2024/03/27)

  • Changed: default value of process_func_applies_sliding_window argument of audinterface.Feature from True to False

  • Fixed: multiprocessing for audinterface.Feature, audinterface.Process, audinterface.ProcessWithContext, audinterface.Segment

  • Removed: deprecated unit argument from audinterface.Feature

Version 1.2.0 (2024/03/21)

  • Added: process_func_args argument to audinterface.Feature.process_file(), audinterface.Feature.process_files(), audinterface.Feature.process_folder(), audinterface.Feature.process_index(), audinterface.Feature.process_signal(), audinterface.Feature.process_signal_from_index(), audinterface.Process.process_file(), audinterface.Process.process_files(), audinterface.Process.process_folder(), audinterface.Process.process_index(), audinterface.Process.process_signal(), audinterface.Process.process_signal_from_index(), audinterface.ProcessWithContext.process_index(), audinterface.ProcessWithContext.process_signal_from_index(), audinterface.Segment.process_file(), audinterface.Segment.process_files(), audinterface.Segment.process_folder(), audinterface.Segment.process_index(), audinterface.Segment.process_signal(), audinterface.Segment.process_signal_from_index(). It allows to temporarily overwrite the process_func_args argument used when instantiating an interface

  • Changed: depend on audeer>=1.18.0

  • Fixed: avoid deprecation warning by replacing pkg_resources internally with importlib.metadata

Version 1.1.0 (2023/07/28)

  • Added: include_root argument to audinterface.Feature.process_folder(), audinterface.Process.process_folder(), audinterface.Segment.process_folder(). Returns relative file path in index if set to False. Default value is True

  • Changed: when audinterface.Feature is instantiated with an audinterface.Segment object that returns an empty index, audinterface.Feature.process_*() no longer return Index([], dtype="object") but MultiIndex([], names=["file", "start", "end"])

  • Fixed: preserve order of start and end values as returned by the segmentation callable in the index returned by audinterface.Segment processing functions

  • Fixed: precision of audinterface.utils.to_timedelta() for pd.Timedelta objects as input, e.g. to_timedelta(pd.Timedelta("0 days 00:00:35.511437999")) now returns Timedelta("0 days 00:00:35.511437999") instead of Timedelta("0 days 00:00:35.511437"). This also affects the output of audinterface.utils.signal_index()

  • Fixed: preserve requested start and end values in process_file(), process_files(), process_folder() methods of audinterface.Process and audinterface.Feature(). Before they were rounded to the next sample in the returned index

Version 1.0.4 (2023/07/13)

  • Changed: require audmath>=1.3.0

  • Changed: require audiofile>=1.3.0

  • Changed: always evenly round start and end to samples in audinterface.utils.read_signal()

  • Fixed: process functions that work on segments are now always processing the identical signal independent if they get the signal as input, like audinterface.Process.process_signal(), or a file, like audinterface.Process.process_file()

Version 1.0.3 (2023/06/06)

  • Added: cache_root argument to audinterface.Segment.process_index()

Version 1.0.2 (2023/05/08)

  • Added: support for Python 3.11

  • Changed: require audformat>=1.0.1

  • Fixed: *.process_index() keeps precision of end values when a segmented index is returned

Version 1.0.1 (2023/03/29)

  • Fixed: do not truncate strings in values returned by process methods of audinterface.Feature

Version 1.0.0 (2023/03/14)

  • Added: preserve_index argument to audinterface.Process.process_index() and audinterface.Feature.process_index()

  • Added: support for Python 3.10

  • Changed: speed up processing methods dealing with multiple files/segments in audinterface.Feature, audinterface.Process, audinterface.ProcessWithContext, and audinterface.Segment

  • Removed: deprecated kwargs argument from audinterface.Feature, audinterface.Process, audinterface.ProcessWithContext, and audinterface.Segment; use the process_func_args argument instead

  • Fixed: require sphinx-audeering-theme>=1.2.1 to ensure the correct theme is used for the public documentation
