Member Function Documentation

template<typename Type >

static Type Decibels::decibelsToGain	(	const Type	decibels,
		const Type	minusInfinityDb = (Type) defaultMinusInfinitydB
	)		[static]

Converts a dBFS value to its equivalent gain level.

A gain of 1.0 = 0 dB, and lower gains map onto negative decibel values. Any decibel value lower than minusInfinityDb will return a gain of 0.

template<typename Type >

static Type Decibels::gainToDecibels	(	const Type	gain,
		const Type	minusInfinityDb = (Type) defaultMinusInfinitydB
	)		[static]

Converts a gain level into a dBFS value.

A gain of 1.0 = 0 dB, and lower gains map onto negative decibel values. If the gain is 0 (or negative), then the method will return the value provided as minusInfinityDb.

template<typename Type >

static String Decibels::toString	(	const Type	decibels,
		const int	decimalPlaces = 2,
		const Type	minusInfinityDb = (Type) defaultMinusInfinitydB
	)		[static]

Converts a decibel reading to a string, with the 'dB' suffix.

If the decibel value is lower than minusInfinityDb, the return value will be "-INF dB".
