LevelRatioUnit enum
Represents units of logarithmic level ratio.
LevelRatioUnit models relative gain or attenuation, not an absolute level. The base unit for internal conversion is decibel (dB).

Values
- decibel → const LevelRatioUnit
-
Decibel (dB), the base unit for level ratio conversions.
const LevelRatioUnit(1, 'dB') - neper → const LevelRatioUnit
-
Neper (Np), using the amplitude convention.
const LevelRatioUnit(LevelRatioFactors.decibelsPerNeper, 'Np')
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- index → int
-
A numeric identifier for the enumerated value.
no setterinherited
- isMetric → bool
-
Returns
falsefor all units, since logarithmic ratio units are not tied to any unit system.no setteroverride - isSI → bool
-
The decibel and neper are non-SI units accepted for use with the SI,
but neither is itself an SI unit, so this always returns
false.no setteroverride - name → String
-
Available on Enum, provided by the EnumName extension
The name of the enum value.no setter - runtimeType → Type
-
A representation of the runtime type of the object.

- symbol → String
-
The display symbol for this level ratio unit.
