audio_falloff_exponent_distance |
gain = (listener_distance / reference_distance) ^ (-falloff_factor) |
audio_falloff_exponent_distance_clamped |
distance = clamp(listener_distance, reference_distance, maximum_distance)
gain = (distance / reference_distance) ^ (-falloff_factor) |
audio_falloff_inverse_distance |
gain = reference_distance / (reference_distance + falloff_factor * (listener_distance – reference_distance)) |
audio_falloff_inverse_distance_clamped |
distance = clamp(listener_distance, reference_distance, maximum_distance)
gain = reference_distance / (reference_distance + falloff_factor * (distance – reference_distance)) |
audio_falloff_linear_distance |
distance = min(distance, maximum_distance)
gain = (1 – falloff_factor * (distance – reference_distance) / (maximum_distance – reference_distance)) |
audio_falloff_linear_distance_clamped |
distance = clamp(listener_distance, reference_distance, maximum_distance)
gain = (1 – falloff_factor * (distance – reference_distance) / (maximum_distance – reference_distance)) |
audio_falloff_none |
gain = 1 |
