「録った声がこもる」「部屋が響きすぎる」——その原因、数字で確かめてみませんか? 吸音材ナビは、拍手一発で部屋の残響時間(RT60)を測定し、宅録・配信に適した響きかどうかを判定するアプリです。吸音材を買う前に、あなたの部屋に本当に必要な量と貼る場所がわかります。 ■ 使い方はかんたん 1. 部屋の中央でアプリを起動 2. 手を1回、強く叩く 3. 減衰カーブと残響時間(RT60)が表示され、用途別の判定が出ます ■ 無料でできること ・残響時間(RT60)の測定(回数無制限) ・低域・中域・高域の帯域別表示 ・配信/ボーカル録音/ミックスの用途別判定と解釈 ・複数回測定のばらつき表示 ■ Pro(買い切り)で解放 ・必要な吸音材の量(平米・枚数・材料別換算) ・貼る場所の配置ガイド(マイク正面・一次反射点など) ・予算目安 ・PDFレポート出力 ・測定履歴の保存とBefore/After比較(貼る前後の効果を数値で確認) ■ ご注意 本アプリは部屋の中の響き(吸音)を測定するアプリです。壁の遮音性能(外への音漏れ)は測定できません。音漏れが気になる方は同じ開発者の「音漏れチェッカー Otomore」をご利用ください。 測定はiPhone内蔵マイクによる簡易測定で、お部屋の傾向を知るための目安です。業務用測定器の代替ではありません。音声は端末内でのみ解析され、保存・送信されることはありません。
