pub fn ratio(left: f32, right: f32) -> f32Expand description
The absolute left/right ratio of two non-negative magnitudes, -1..=1,
negative to the left.
The one place the floor is applied, so the whole-mix field and the
per-band one cannot disagree about what silence reads: exactly 0 when the
larger of the two sits below WAVE_FLOOR, rather than a ratio of noise.
The division itself is floored as well as guarded, so it is total even if
the guard above it ever moves.
