Public methods
getGainFactorAt
abstract float getGainFactorAt(
@IntRange(from = 0) long index,
@IntRange(from = 1) long duration
)
Returns the gain factor within [0f; 1f] to apply to an audio sample for a specific fade shape.
Position and duration are unit agnostic and work as a numerator/denominator pair.
You can implement a basic linear fade as follows:
public float getGainFactorAt(long index, long duration) {
return (float) index / duration;
}
