cChroma

Description

This component computes CHROMA features from a semi-tone scaled spectrum generated by the 'cTonespec' component.

Type hierarchy

cDataProcessor → cVectorProcessor → cChroma

Fields

• nameAppend (string) [default: chroma]

  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.

• octaveSize (numeric) [default: 12.0]

  The size of an octave, i.e. the number of output bins, or the interval to which the input bins are mapped via warping.

• silThresh (numeric) [default: 0.001]

  Chroma 'floor', i.e. silence threshold. If at least on element of the (unnormalised) chroma vector falls below the threshold, the vector will not be normalised, and a 0 vector will be output instead.
