Presets provides an object interface that can override common default parameter settings for all functions within a target module or package.

It’s simple to use. Simply construct a Preset object with the target module as an argument, then set the default parameters via a dict-like interface. After that, your new object will act just as the target module, but it replaces the default arguments of any functions with values that you set.


>>> import librosa as _librosa
>>> from presets import Preset
>>> librosa = Preset(_librosa)
>>> librosa['sr'] = 44100
>>> librosa['n_fft'] = 4096
>>> librosa['hop_length'] = 1024
>>> y, sr = librosa.load(librosa.util.example_audio_file())
>>> sr
>>> stft = librosa.stft(y)
