SUMMARY
SPECCHORD imposes transposed versions of the sound onto the original frequencies.

MODES
 1. Harmonise: make chord preserving time but not spectral envelope.
 2. Chord with formants (freq): make chord preserving formants extracted by frequency.
 3. Chord with formants (pitch): make chord preserving formants extracted by pitch.

PARAMETERS
  transpose: Textfile of transposition values in semitones
    Range: -48 to +48 semitones
  [low freq]: filter out all frequencies lower than this
    Range: 20-20 kHz
  [high freq]: filter out all frequencies higher than this
    Range: 20-20kHz
  [channels]: No. of frequency channels per point used to extract spectral contour
    Range: 1-100  (fewer is more accurate)
  [bands]: No. of pitch bands per octave used to extract spectral contour
    Range: 1-12 (greater is more accurate)


OPTION:
  • Fuller spectrum
 
NOTES
The aural results are not the same as you get with STACK or TRANSPOSE. SpecChord appears to duplicate just the spectral frequency content, whereas each TRANSPOSE has a separate spectral envelope (dynamic contour).
