Audio Echo Filter 在给定的__延时 (Delay)__ 之后重复声音,并根据__衰减率 (Decay Ratio)__ 衰减重复的声音。
属性: | 功能: |
---|---|
Delay | 回声延时,以 ms 为单位。范围从 10 到 5000。默认值为 500。 |
Decay Ratio | 每次延时的回声衰减。范围从 0 到 1。1.0 表示无衰减,0.0 表示完全衰减(例如,简单的 1 行延时)。默认值为 0.5。 |
Wet Mix | 要传递到输出的回声信号量。范围从 0.0 到 1.0。默认值为 1.0。 |
Dry Mix | 要传递到输出的原始信号量。范围从 0.0 到 1.0。默认值为 1.0。 |
Wet Mix 值决定了滤波信号的幅度,__Dry Mix__ 决定了未过滤声音输出的幅度。
坚硬的表面会反射声音的传播。例如,使用音频回声滤波器 (Audio Echo Filter) 可使大峡谷效果更加逼真。
根据闪电和雷声可知声音的传播速度比光慢。要模拟此情况,请为事件声音应用 Audio Echo Filter,将 Wet Mix 设置为 0.0 并将 Delay 调制为音频源到音频监听器之间的距离。
