cCens¶

Description¶

This component computes CENS (energy normalised and smoothed chroma features) from raw Chroma features generated by the 'cChroma' component.

nameAppend (string) [default: CENS]

A string suffix to append to the input field names (default: empty)
copyInputName (numeric) [default: 0.0]

1 = copy the input name (and optionally append a suffix, see 'nameAppend' option), 0 = discard the input name and use only the 'nameAppend' string as new name.
window (string) [default: han]

The window function to use for temporal CENS smoothing; one of these: han (Hanning), ham (Hamming), bar (Bartlett)
downsampleRatio (numeric) [default: 10.0]

The integer ratio at which to downsample the resulting sequence of vectors. I.e. a value of 4 will average 4 frames and output 1 CENS frame.
winlength (numeric) [default: 41.0]

The length of the CENS smoothing window, in frames.
winlength_sec (numeric) [default: 0.41]

The length of the CENS smoothing window, in seconds. This will be rounded upwards (ceil) to the closest length in frames. It overrides winlength, if set.
l2norm (numeric) [default: 1.0]

1/0 = enable/disable normalisation of CENS vectors by their L2-norm.
