Unity SFX Reverb Effect プリセットメモ
Unityのオーディオ機能のAudio Mixerから追加出来る標準リバーブエフェクトであるSFX Reverb Effect。
多彩な表現が出来ますが、パラメーターが多すぎて、DAWソフトウェアで音楽を作ったことがある人、オーディオに興味がある人じゃないと設定難しいですよね。公式ドキュメントを見ても、実際に音がどう変わるのか全然想像がつきません。
以下、公式ドキュメントより抜粋
↑SFX Reverb Effectのパラメーター
| プロパティ | 機能 |
|---|---|
| Dry Level | 出力中のドライ信号のミックスレベル（単位：mB）–10000.0 ~ 0.0 デフォルト 0 mB |
| Room | 低周波数の Room エフェクトレベル（単位：mB） –10000.0 ~ 0.0 デフォルト –10000.0 mB |
| Room HF | 高周波数の Room エフェクトレベル（単位：mB） –10000.0 ~ 0.0 デフォルト 0.0 mB |
| Decay Time | 低周波数での残響減衰時間 (単位: 秒)。範囲は 0.1 から 20 まで。デフォルトは 1 です。 |
| Decay HF Ratio | 高周波から低周波にする低周波減衰時間の比率。範囲は 0.1 から 2 まで。デフォルトは 0.5 です。 |
| Reflections | Room エフェクト に対する相対的な初期反射のレベル（単位：mB） –10000.0 ~ 1000.0 デフォルト –10000.0 mB |
| Reflect Delay | Room エフェクト に対する相対的な、初期反射のディレイタイム（単位：秒） 0.0 ~ 0.3 デフォルト 0.02 |
| Reverb | Room エフェクトに対する相対的な、後期残響のレベル（単位：mB） –10000.0 ~ 2000.0 デフォルト 0.0 mB |
| Reverb Delay | 初期反射に対する相対的な、後期残響のディレイタイム（単位：秒） 0.0 ~ 0.1 デフォルト 0.04 mB |
| Diffusion | パーセントとして示すリバーブの拡散（エコー密度）0.0 ~ 100.0 デフォルト 100.0% |
| Density | パーセントとして示すリバーブの拡散（モーダル密度） 0.0 ~ 100.0 デフォルト 100.0% |
| HFReference | 高周波数（単位:Hz） 20.0 ~ 20000.0 デフォルト 5000.0 Hz |
| Room LF | Room エフェクトの低周波レベル（単位：mB） –10000.0 ～ 0.0 デフォルト 0.0 mB |
| LFReference | 低周波数（単位:Hz） 20.0 ～ 1000.0 デフォルト 250.0 Hz |
実はこれ、Audio SourceやAuido Listenerに直接追加できるコンポーネント、Audio Reverb Filterと機能は同じです。そして、こっちにはReverb Presetからプリセットを選べるんです。（なんでAudio Mixerでは出来ないのかわかりませんが。）

SFX Reverb Effectでもプリセットから選べると便利なのですが、
現状、自分で編集していくしかないので、プリセットを全部メモりました。

余談
パラメーターの順番が、SFX Reverb EffectとReverb Filterでは違いますが、Reverb Filterのほうが自然だしどう見ても正しいですよね。このパラメーターの順番もSFX Reverbを使いにくくしている一因だと思います。Unity開発チームにはぜひ直してほしいところです。
