오디오 저대역 필터(Audio Low Pass Filter) 는 AudioSource의 낮은 프리퀀시 또는 AudioListener에 도달하는 모든 사운드를 통과시키는 동시에 Cutoff Frequency 보다 높은 프리퀀시는 제거합니다.
프로퍼티: | 기능: |
---|---|
Cutoff Frequency | 로우패스 컷오프 프리퀀시(단위: Hz)(범위: 0.0–22000.0, 디폴트값 = 5000.0). |
Lowpass Resonance Q | 로우패스 공명 품질 값(범위: 1.0–10.0, 디폴트값 = 1.0). |
Lowpass Resonance Q(Highpass Resonance Quality Factor 줄임말)는 필터의 셀프 공명이 줄어드는 정도를 결정합니다. 로우패스 공명 품질이 높다는 것은 낮은 에너지 손실률을 나타내며, 이는 진동이 더 천천히 사라진다는 것을 의미합니다.
Audio Low Pass Filter 에는 이와 관련된 Rolloff 커브가 있으며, 이로 인해 AudioSource와 AudioListener 간 거리의 Cutoff Frequency 를 설정할 수 있습니다.
환경에 따라 사운드 전달이 크게 차이납니다. 예를 들어, 시각적 안개 효과를 보완하려면 오디오 리스너에 엷은 로우 패스를 추가해야 합니다. 도어 뒤에서 방출되는 사운드의 프리퀀시가 높을 경우 도어 밖으로 필터링되어 리스너에게까지 도달하지 못합니다. 시뮬레이션 하려면 도어를 열 때 컷오프 프리퀀시를 변경해야 합니다.
