pumpp.feature.FeatureExtractor

class pumpp.feature.FeatureExtractor(name, sr, hop_length, conv=None)[source]

The base feature extractor class.

Attributes

name (str) The name for this feature extractor
sr (number > 0) The sampling rate of audio for analysis
hop_length (int > 0) The hop length between analysis frames
conv ({‘tf’, ‘th’, ‘channels_last’, ‘channels_first’, None}) convolution dimension ordering: - ‘channels_last’ for tensorflow-style 2D convolution - ‘tf’ equivalent to ‘channels_last’ - ‘channels_first’ for theano-style 2D convolution - ‘th’ equivalent to ‘channels_first’ - None for 1D or non-convolutional representations
__init__(name, sr, hop_length, conv=None)[source]
