dbu

Acoustic U-weighting function.

Syntax

dbu(x, y, [, reference])

Argument

x
The frequency vector of the input curve in Hertz.
y
The input vector of the input curve to be weighted.
[, reference]
An optional reference value. 1.0 is used when no reference value is specified.

Example

Curve Math Vectors Result
x = c1.x

y = dbu(c1.x, c1.y)

 Given c1, a U-weighted frequency curve is created.

Comments

The dbu function returns the U-weighted frequency curve for the input curve. The U-weighting dampens the ultra-sonic components of the input curve.
