dba
Acoustic A-weighting function.
Syntax
dba(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
|
Given c1, an A-weighted frequency curve is created. |
Comments
The dba function returns the A-weighted frequency curve for the input curve. The A-weighting dampens the non-audible components of the input curve.
x=c1.x
y=20*log10(dba(c1.x, c1.y, reference))
