pumpp.feature.Tempogram

class pumpp.feature.Tempogram(name, sr, hop_length, win_length, conv=None)

Tempogram: the short-time autocorrelation of the accent signal

Attributes:

name : str

The name of this feature extractor

sr : number > 0

The sampling rate of audio

hop_length : int > 0

The hop length of analysis windows

win_length : int > 0

The length of the analysis window (in frames)

__init__(name, sr, hop_length, win_length, conv=None)

Initialize self. See help(type(self)) for accurate signature.
