Vector convert power or amplitude to decibels; single precision.
- macOS 10.4+
Single-precision real input vector
Pointer to single-precision real input scalar: zero reference
Single-precision real output vector
The number of elements to process
Power (0) or amplitude (1) flag
Performs the following operation. α is 20 if
F is 1, or 10 if
F is 0.
Converts inputs from vector
A to their decibel equivalents, calculated in terms of power or amplitude according to flag
F. As a relative reference point, the value of input scalar
*B is considered to be zero decibels.
