• 13 Nov 2021 - 0.3.6

  • bugfix/pad end tflite #131

• 18 March 2021 - 0.3.5

  • Add kapre.time_frequency_tflite which uses tflite for a faster CPU inference.

• 29 Sep 2020 - 0.3.4

  • Fix a bug in kapre.backend.get_window_fn(). Previously, it only correctly worked with None input and an error was raised when non-default value was set for window_name in any layer.

  • kapre.augmentation is added
  • kapre.time_frequency.ConcatenateFrequencyMap is added
  • kapre.composed.get_frequency_aware_conv2d is added
  • In STFT and InverseSTFT, keyword arg window_fn is renamed to window_name and it expects string value, not function. - With this update, models with Kapre layers can be loaded with h5 file format.
  • kapre.backend.get_window_fn is added

• 28 Aug 2020 - 0.3.2

  • kapre.signal.Frame and kapre.signal.Energy are added
  • kapre.signal.LogmelToMFCC is added
  • kapre.signal.MuLawEncoder and kapre.signal.MuLawDecoder are added
  • kapre.composed.get_stft_magnitude_layer() is added

• 21 Aug 2020 - 0.3.1

  • Inverse STFT is added

• 15 Aug 2020 - 0.3.0

  • Breaking and simplifying changes with Tensorflow 2.0 and more tests. Some features are removed.

• 29 Jul 2020 - 0.2.0

  • Change melspectrogram filterbank from norm=1 to norm=’slaney’ (w.r.t. Librosa) due to the update from Librosa (https://github.com/keunwoochoi/kapre/issues/77)

  This would change the behavior of melspectrogram slightly. - Bump librosa version to 0.7.2 or higher.
