Public methods
getGainFactorAtSamplePosition
abstract float getGainFactorAtSamplePosition(
@IntRange(from = 0) long samplePosition,
@IntRange(from = 1) int sampleRate
)
Returns a gain factor between [0f; 1f] to apply at the given sample position relative to sampleRate.
Returned values must not change for the same pair of parameter values within the lifetime of the instance.
isUnityUntil
abstract long isUnityUntil(
@IntRange(from = 0) long samplePosition,
@IntRange(from = 1) int sampleRate
)
Returns the exclusive upper limit of the range starting at samplePosition where the gain value is 1f (unity), or TIME_UNSET if samplePosition does not correspond to a gain of 1f.
If the range continues until the end of the stream, this method returns TIME_END_OF_SOURCE.
Returned values must not change for the same pair of parameter values within the lifetime of the instance.
