Audio Echo Filter は、所定の「 Delay 」後に音声を繰り返し、「 Decay Ratio 」に基づいて、繰り返しを減衰します。
プロパティー | 機能 |
---|---|
Delay | ミリ秒単位のディレイを設定する。10 から 5000 の間で設定(デフォルトは 500 )。 |
Decay Ratio | 遅延ごとのエコー減衰 0 ~ 1 1.0=減衰なし 0.0=合計減衰(1 行だけの減衰) デフォルト = 0.5 |
Wet Mix | 出力に渡すエコー信号の音量。0 から 1 の間で設定(デフォルトは 1 )。 |
Dry Mix | 出力に渡す元の信号の音量。0 から 1 の間で設定(デフォルトは 1 )。 |
Wet Mix はフィルタリングされた信号の振幅を決定しますが、Dry Mix は、フィルタリングされていない音声出力の振幅を決定します。
固い平面は音の伝播を反映する。たとえば、大規模な峡谷のこだまは、Audio Echo Filter により再現できます。
落雷や雷を経験すればわかるように、音は光より遅く伝播します。これをシミュレートするには、オーディオエコーフィルターをイベントサウンドに追加し、Wet Mix に 0.0 を設定し、Delay の値を Audio Source と Audio Listener の間の距離に調節します。
