A loudness measurement UGen, using Zwicker bands. One value in Phon per window is output.
The original algorithm outputs a
minimum value of 3.0. This is still the case, but if a window is entirely
silent (all values are zero), the output value is also 0.0. Thus one may
either distinguish between these two cases, or just treat output value
of <= 3.0 as silences.
- Value parameters:
- diffuse
whether to assume diffuse field (
1) or free field (0)- in
the signal to analyse
- sampleRate
sample rate of the input signal
- size
the window size for which to calculate values
- spl
the reference of 0 dBFS in decibels
