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.

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.

Converts a decibel reading to a string.
By default the returned string will have the 'dB' suffix added, but this can be removed by setting the shouldIncludeSuffix argument to false. If a customMinusInfinityString argument is provided this will be returned if the value is lower than minusInfinityDb, otherwise the return value will be "-INF".
