SPCOR

[GENERIC-FUNCTION]


OM-Chant
Function Reference
ARGUMENTS:
  - AMPLIST list of initial formants' amplitudes [default = (1.0 1.0 1.0)]
  - BWLIST list of bandwidths [default = (36.97 49.02 69.69)]
  - TEXLIST list of attack times (sec.) [default = (0.002 0.002 0.002)]

Description:

SPCOR adjusts the formants amplitudes <amplist> according to the duration of the attacks of the FOFs (<texlist>) and the bandwidths of the respective formants (<bwlist>).

When the formants have different bandwidths and skirt-widths (skirt-width is directly related to the attack time -- see AUTOTEX function) their respective corresponding energy in the spectrum is modified due to superposition effects.
