        Spectrum

FFT based frequency analysis of audio frames.

Instance Methods

[hide private]

__init__(self, fft_size, samplerate, blocksize, totalframes, lower, higher, window_function=None)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

process(self, frames, eod, spec_range=120.0)
Returns a tuple containing the spectral centroid and the spectrum (dB scales) of the input audio frames.

process(self, frames, eod, spec_range=120.0)

source code

Returns a tuple containing the spectral centroid and the spectrum (dB scales) of the input audio frames. FFT window sizes are adatable to the input frame size.
