computePinkNoiseGain()

float fl::audio::computePinkNoiseGain ( float freq_hz, float f_ref )

inline

Compute pink noise compensation gain for a single frequency.

Pink noise has 1/f spectral density → equal power per octave. To flatten it: multiply by sqrt(f / f_ref).

Parameters

freq_hz	Bin center frequency in Hz
f_ref	Reference frequency (typically geometric mean of all bins)

Returns

Compensation gain factor

    if (freq_hz <= 0.0f || f_ref <= 0.0f) return 1.0f;
    return fl::sqrtf(freq_hz / f_ref);
