青空の下でギターを弾くための、シンプルなチューナーです。 弦を鳴らすだけで、6弦 E2 から 1弦 E4 まで自動で音を判別します。針はリアルタイムに動き、合っていれば緑、ずれていれば黄から赤へと色が変わります。数字と色と針だけで、迷わずチューニングできます。 ■ 通信しません ネットワーク通信の処理は一切含まれていません。マイクが拾った音は端末の中だけで解析され、録音も保存も送信もしません。機内モードのまま、電波の届かない場所でも使えます。 ■ 見たまま合わせるだけ ・音名と弦番号、周波数を大きく表示します ・±5 セント以内で緑に変わり、軽い振動でも知らせます ・大きく外れていても針は止まりません。ペグを回すたびに動くので、締めている手応えがそのまま画面に出ます ・チューニング中は画面が自動で暗くなりません ■ 基準ピッチを変えられます A4 = 415.0〜466.0Hz を 0.1Hz 単位で設定できます。桁ごとに上下ボタンがあるので、432Hz などにもすばやく合わせられます。設定した値は次に開いたときも保たれます。 ■ 標準チューニング (A4 = 440Hz のとき) 6弦 E2 (82.41Hz) / 5弦 A2 (110.00Hz) / 4弦 D3 (146.83Hz) 3弦 G3 (196.00Hz) / 2弦 B3 (246.94Hz) / 1弦 E4 (329.63Hz) 余計な機能はありません。開いて、弾いて、合わせるだけです。
